public final class CipherSuite

extends java.lang.Object

implements java.io.Serializable

A CipherSuite defines a cipher specification supported in SSL and TLS. This includes:

• name of the cipher suite
• exportability status (limit on the key size used for key exchange)
• name of the key exchange algorithm
• name of the cipher algorithm
• name of the hash algorithm
• a 2 byte identifier for the cipher suite
• the number of bytes that are used for generating the write keys
• the number of bytes actually fed into the encryption algorithm
• IV size (CBC mode)

Constructor Detail

CipherSuite

public CipherSuite(java.lang.String cipherSuiteName,
                   java.lang.String keyExchangeAlgorithm,
                   java.lang.String cipherAlgorithm,
                   java.lang.String hashAlgorithm,
                   int id,
                   int keyMaterial,
                   int IVSize)

Create a new user defined ciphersuite. It can be used to define custom private ciphersuites that use e.g. Blowfish as symmetric cipher or to define one that uses e.g. TripleDES with MD5. However, it is currently not possible to add new key exchange algorithms, new hash algorithms, or to define an exportable ciphersuite.

Parameters:

cipherSuiteName - the name of the ciphersuite

keyExchangeAlgorithm - the keyExchangeAlgorithm, e.g. RSA

cipherAlgorithm - the name and mode of the symmetric cipher per JCE convention, e.g. DES/CBC/NoPadding (always use NoPadding)

hashAlgorithm - either SHA or MD5

id1 - high byte of the ciphersuite id. Should be 0xFF for private ciphersuites.

id2 - low byte of the ciphersuite id.

keyMaterial - size of the key to be used for the symmetric cipher in bytes, e.g. 16.

IVSize - blocksize of the cipher in bytes for block ciphers or 0 for stream ciphers.
