Method Detail

getCipherAlgorithmName

String getCipherAlgorithmName()

Returns:

the algorithm name of created ciphers (ie: AES, CAST5, ...)

getIVSize

int getIVSize()

Returns:

the cipher block size (in bytes) that should be used to generate an IV or -1 if the cipher does not use an initialization vector.

getKeySize

int getKeySize()

Returns:

the recommended default key size of created ciphers (in bytes), usually the largest one supported.

getSupportedKeySizes

int[] getSupportedKeySizes()

Returns:

an array of the supported key sizes of created ciphers (in bytes).

isSupportedKeySize

boolean isSupportedKeySize(int keySize)

Parameters:

keySize - the size in bytes of a proposed key.

Returns:

true if the proposed key size is supported.
