) AlgorithmsNote: The Sun Provider Documentation contains specific provider and algorithm information.
The JDK Security API requires and uses a set of standard names for algorithms, certificate and keystore types. This specification establishes the following names as standard names.
In some cases naming conventions are given for forming names
that are not explicitly listed, to facilitate name consistency
across provider implementations. Items in angle brackets (such as
<digest>
and <encryption>
)
are placeholders to be replaced by a specific message digest,
encryption algorithm, or other name.
Note: Standard names are not case-sensitive.
This document includes corresponding lists of standard names relevant to the following security subareas:
AlgorithmParameterGenerator
AlgorithmsThe algorithm names in this section can be specified when
generating an instance of
AlgorithmParameterGenerator
.
Algorithm Name | Description |

DiffieHellman | Parameters for use with the Diffie-Hellman algorithm. |
DSA | Parameters for use with the Digital Signature Algorithm. |
AlgorithmParameters
AlgorithmsThe algorithm names in this section can be specified when
generating an instance of AlgorithmParameters
.

CertificateFactory
TypesThe type in this section can be specified when generating an
instance of CertificateFactory
.
Type | Description |

X.509 | The certificate type defined in X.509, also available via RFC 3280 |
CertPathBuilder
AlgorithmsThe algorithm in this section can be specified when generating
an instance of CertPathBuilder

Algorithm Name | Description |
---|---|
PKIX | The PKIX certification path validation algorithm as defined in
the ValidationAlgorithm service attribute.

validation algorithm. |
The following encodings may be passed to the
getEncoded
method of CertPath
or the
generateCertPath(InputStream inStream, String
encoding)
method of CertificateFactory
.
Encoding | Description |
---|---|
PKCS7 | A PKCS#7 SignedData object, with the only significant field
being certificates. In particular, the signature and the contents
are ignored. If no certificates are present, a zero-length
CertPath is assumed. Warning: PKCS#7 does not maintain
the order of certificates in a certification path. This means that
if a CertPath is converted to PKCS#7 encoded bytes and
then converted back, the order of the certificates may change,
potentially rendering the CertPath invalid. Users
should be aware of this behavior. See RSA Security for
details on PKCS7. |
PkiPath | an ASN.1 DER encoded sequence of certificates, defined as
follows:
PkiPath ::= SEQUENCE OF CertificateWithin the sequence, the order of certificates is such that the subject of the first certificate is the issuer of the second certificate, and so on. Each certificate in PkiPath
shall be unique. No certificate may appear more than once in a
value of Certificate in PkiPath . The
PkiPath format is defined in defect report 279 against
X.509 (2000) and is incorporated into Technical Corrigendum 1 (DTC
2) for the ITU-T Recommendation X.509 (2000). See the ITU website for
details. |

The following names can be specified as the mode
component in a transformation when requesting
an instance of Cipher
.
Algorithm Name | Description |
---|---|
NONE | No mode. |
CBC | Cipher Block Chaining Mode, as defined in FIPS PUB 81. |
CFB, CFBx | Cipher Feedback Mode, as defined in FIPS PUB
81. Using modes such as CFB and OFB, block ciphers can encrypt data in units smaller than the cipher's actual block size. When requesting such a mode, you may optionally specify the number of bits to be processed at a time by appending this number to the mode name as shown in the "DES/CFB8/NoPadding" and "DES/OFB32/PKCS5Padding" transformations. If no such number is specified, a provider-specific default is used. (For example, the SunJCE provider uses a default of 64 bits for DES.) Thus, block ciphers can be turned into byte-oriented stream ciphers by using an 8-bit mode such as CFB8 or OFB8. |
CTR | A simplification of OFB, Counter mode updates the input block as a counter. |
CTS | Cipher Text Stealing, as described in Bruce Schneier's book Applied Cryptography-Second Edition, John Wiley and Sons, 1996. |
ECB | Electronic Codebook Mode, as defined in FIPS PUB 81. |
OFB, OFBx | Output Feedback Mode, as defined in FIPS PUB
81. Using modes such as CFB and OFB, block ciphers can encrypt data in units smaller than the cipher's actual block size. When requesting such a mode, you may optionally specify the number of bits to be processed at a time by appending this number to the mode name as shown in the "DES/CFB8/NoPadding" and "DES/OFB32/PKCS5Padding" transformations. If no such number is specified, a provider-specific default is used. (For example, the SunJCE provider uses a default of 64 bits for DES.) Thus, block ciphers can be turned into byte-oriented stream ciphers by using an 8-bit mode such as CFB8 or OFB8. |
PCBC | Propagating Cipher Block Chaining, as defined by Kerberos V4. |
The following names can be specified as the padding
component in a transformation when requesting
an instance of Cipher
.
Algorithm Name | Description |
---|---|
NoPadding | No padding. |
ISO10126Padding | This padding for block ciphers is described in 5.2 Block Encryption Algorithms in the W3C's "XML Encryption Syntax and Processing" document. |
OAEPPadding, OAEPWith<digest>And<mgf>Padding | Optimal Asymmetric Encryption Padding scheme defined in PKCS1,
where <digest> should be replaced by the message digest and
<mgf> by the mask generation function. Examples:
OAEPWithMD5AndMGF1Padding and
OAEPWithSHA-512AndMGF1Padding. If OAEPPadding is used, Cipher objects
are initialized with a
javax.crypto.spec.OAEPParameterSpec object to supply
values needed for OAEPPadding. |
PKCS1Padding | The padding scheme described in PKCS #1, used with the RSA algorithm. |
PKCS5Padding | The padding scheme described in RSA Laboratories, "PKCS #5: Password-Based Encryption Standard," version 1.5, November 1993. |
SSL3Padding | The padding scheme defined in the SSL Protocol Version 3.0,
November 18, 1996, section 5.2.3.2 (CBC block cipher):
block-ciphered struct { opaque content[SSLCompressed.length]; opaque MAC[CipherSpec.hash_size]; uint8 padding[ GenericBlockCipher.padding_length]; uint8 padding_length; } GenericBlockCipher;The size of an instance of a GenericBlockCipher must be a multiple of the block cipher's block length. The padding length, which is always present, contributes to the padding, which implies that if: sizeof(content) + sizeof(MAC) % block_length = 0,padding has to be (block_length - 1) bytes long, because of the existence of padding_length .This makes the padding scheme similar (but not quite) to PKCS5Padding, where the padding length is encoded in the padding (and ranges from 1 to block_length). With the SSL scheme, the sizeof(padding) is encoded in the always present padding_length and therefore ranges from 0 to
block_length-1. |

A cryptographic service is always associated with a particular
algorithm or type. For example, a digital signature service is
always associated with a particular algorithm (for example, DSA),
and a CertificateFactory
service is always associated
with a particular certificate type (for example, X.509).
The attributes in this section are for cryptographic services. The service attributes can be used as filters for selecting providers.
Both the attribute name and value are case-insensitive.

ValidationAlgorithm | The name of the specification that defines the certification
path validation algorithm that an implementation of
CertPathBuilder or CertPathValidator
supports. RFCs should be specified as "RFC#" (ex: "RFC3280") and
Internet Drafts as the name of the draft (ex:
"draft-ietf-pkix-rfc2560bis-01.txt"). Values for this attribute
that are specified as selection criteria to the
Security.getProviders method will be compared using
the String.equalsIgnoreCase method. All PKIX
implementations of CertPathBuilder and
CertPathValidator should provide a value for this
attribute. |
LDAPSchema | The name of the specification that defines the LDAP schema that
an implementation of an LDAP CertStore uses to
retrieve certificates and CRLs. The format and semantics of this
attribute is the same as described for the ValidationAlgorithm
attribute. All LDAP implementations of CertStore
should provide a value for this attribute. |

The ECDSA signature algorithms as defined in ANSI
X9.62.
Note:"ECDSA" is an ambiguous name for the "SHA1withECDSA" algorithm and should not be used. The formal name "SHA1withECDSA" should be used instead. |
<digest>with<encryption> | Use this to form a name for a signature algorithm with a
particular message digest (such as MD2 or MD5) and algorithm (such
as RSA or DSA), just as was done for the explicitly defined
standard names in this section (MD2withRSA, and so on).
For the new signature schemes defined in PKCS #1 v 2.0, for which the <digest>with<encryption> form is insufficient, <digest>with<encryption>and<mgf> can be used to form a name. Here, <mgf> should be replaced by a mask generation function such as MGF1. Example: MD5withRSAandMGF1. |

The following list contains the standard JSSE cipher suite
names. Over time, various groups have added additional cipher
suites to the SSL/TLS namespace. Some JSSE cipher suite names were
defined before TLSv1.0 was finalized, and were therefore given the
SSL_
prefix. The names mentioned in the TLS RFCs
prefixed with TLS_
are functionally equivalent to the
JSSE cipher suites prefixed with SSL_

TLS_EMPTY_RENEGOTIATION_INFO_SCSV
is a new
pseudo-cipher suite to support RFC 5746. Read the Transport
Layer Security (TLS) Renegotiation Issue section of the JSEE
Reference Guide for more information.
The keyType
parameter passed to the
chooseClientAlias
, chooseServerAlias
,
getClientAliases
, and getServerAliases
methods of X509KeyManager
specifies the public key
types. Each row of the table that follows lists the standard name
that should be used for keyType
, given the specified
certificate type.
Name | Certificate Type |
---|---|
RSA | RSA |
DSA | DSA |
DH_RSA | Diffie-Hellman with RSA signature |
DH_DSA | Diffie-Hellman with DSA signature |
EC | Elliptic Curve |
EC_EC | Elliptic Curve with ECDSA signature |
EC_RSA | Elliptic Curve with RSA signature |
The protocols
parameter passed to the
setEnabledProtocols
method of SSLSocket
specifies the protocol versions to be enabled for use on the
connection. The table that follows lists the standard names that
can be passed to setEnabledProtocols
or that may be
returned by the SSLSocket getSupportedProtocols
and
getEnabledProtocols
methods.
Name | Protocol |
---|---|
SSLv2 | SSL version 2 protocol |
SSLv3 | SSL version 3 protocol |
TLSv1 | TLS version 1.0 protocol (defined in RFC 2246) |
TLSv1.1 | TLS version 1.1 protocol (defined in RFC 4346) |
TLSv1.2 | TLS version 1.2 protocol (defined in RFC 5246) |
SSLv2Hello | Currently, the SSLv3, TLSv1, and TLSv1.1 protocols allow you to
send SSLv3, TLSv1, and TLSv1.1 hellos encapsulated in an SSLv2
format hello. For more details on the reasons for allowing this
compatibility in these protocols, see Appendix E in the appropriate
RFCs (previously listed). Note that some SSL/TLS servers do not support the v2 hello format and require that client hellos conform to the SSLv3 or TLSv1 client hello formats. The SSLv2Hello option controls the SSLv2 encapsulation. If SSLv2Hello is disabled on the client, then all outgoing messages will conform to the SSLv3/TLSv1 client hello format. If SSLv2Hello is disabled on the server, then all incoming messages must conform to the SSLv3/TLSv1 client hello format. |
The authType
parameter passed to the
checkClientTrusted
and checkServerTrusted
methods of X509TrustManager
indicates the
authentication type. The table that follows specifies what standard
names should be used for the client or server certificate
chains.
Client or Server Certificate Chain | Authentication Type Standard Name |
---|---|
Client | Determined by the actual certificate used. For instance, if
RSAPublicKey is used, the authType should be
"RSA". |
Server | The key exchange algorithm portion of the cipher suites
represented as a String, such as "RSA" or "DHE_DSS". Note: For some
exportable cipher suites, the key exchange algorithm is determined
at runtime during the handshake. For instance, for
TLS_RSA_EXPORT_WITH_RC4_40_MD5, the authType should be
"RSA_EXPORT" when an ephemeral RSA key is used for the key
exchange, and "RSA" when the key from the server certificate is
used. Or it can take the value "UNKNOWN". |
The Java SE 7 release supports endpoint identification
algorithms for TLS 1.2. The algorithm name can be passed to the
setEndpointIdentificationAlgorithm()
method of
javax.net.ssl.SSLParameters
. The following table shows
the currently recognized names.
Endpoint Identification Algorithm Name |

This section specifies details concerning some of the algorithms defined in this document. Any provider supplying an implementation of the listed algorithms must comply with the specifications in this section.
To add a new algorithm not specified here, you should first survey other people or companies supplying provider packages to see if they have already added that algorithm, and, if so, use the definitions they published, if available. Otherwise, you should create and make available a template, similar to those found in this section, with the specifications for the algorithm you provide.
The following table shows the fields of the algorithm specifications.

This section defines the security algorithm requirements for Java SE 7 implementations. These requirements are intended to improve the interoperability of Java SE 7 implementations and applications that use these algorithms.
Note that the requirements in this section are not a measure of the strength or security of the algorithm. For example, recent advances in cryptanalysis have found weaknesses in the strength of the MD5 MessageDigest algorithm. It is your responsibility to determine whether the algorithm meets the security requirements of your application.
Every implementation of the Java SE 7 platform must support the specified algorithms in the table that follows. These requirements do not apply to 3rd party providers. Consult the release documentation for your implementation to see if any other algorithms are supported.

type or SecureRandom
algorithm is required; however, an implementation-specific default
must be provided.
[2] A TLSv1 implementation must support the cipher suite SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA as defined in RFC 2246 and the special signaling cipher suite TLS_EMPTY_RENEGOTIATION_INFO_SCSV for safe renegotiation as defined in RFC 5746.
Every implementation of the Java SE 7 platform must support the specified XML Signature algorithms in the table that follows. These requirements do not apply to 3rd party providers. Consult the release documentation for your implementation to see if any other algorithms are supported.
