getKeySize

Method Detail

getTransformation

java.lang.String getTransformation()

Returns:

The actual transformation used - e.g., AES/CBC/NoPadding

getIVSize

int getIVSize()

Returns:

Size of the initialization vector (in bytes)

getCipherBlockSize

int getCipherBlockSize()

Returns:

Size of block data used by the cipher (in bytes). For stream ciphers this value is (currently) used to indicate some average work buffer size to be used for the automatic re-keying mechanism described in RFC 4253 - Section 9

getKdfSize

int getKdfSize()

Returns:

The block size (in bytes) used to derive the secret key for this cipher
