Method Detail

checkSupportedKeySize

void checkSupportedKeySize(int keyLength)
                    throws java.security.InvalidKeyException

Description copied from class: OpenSSLCipher

Checks whether the cipher supports this particular keySize (in bytes) and throws InvalidKeyException if it doesn't.

Specified by:

checkSupportedKeySize in class OpenSSLCipher

Throws:

java.security.InvalidKeyException

getBaseCipherName

java.lang.String getBaseCipherName()

Description copied from class: OpenSSLCipher

Returns the standard name for the particular algorithm.

Specified by:

getBaseCipherName in class OpenSSLCipher

getCipherBlockSize

int getCipherBlockSize()

Specified by:

getCipherBlockSize in class OpenSSLCipher

getParameterSpec

protected java.security.spec.AlgorithmParameterSpec getParameterSpec(java.security.AlgorithmParameters params)
                                                              throws java.security.InvalidAlgorithmParameterException

Overrides:

getParameterSpec in class OpenSSLCipher

Throws:

java.security.InvalidAlgorithmParameterException

engineGetParameters

protected java.security.AlgorithmParameters engineGetParameters()

Overrides:

engineGetParameters in class OpenSSLCipher

getOutputSizeForFinal

int getOutputSizeForFinal(int inputLen)

Description copied from class: OpenSSLCipher

The size of output if doFinal() is called with this inputLen. If padding is enabled and the size of the input puts it right at the block size, it will add another block for the padding.

Overrides:

getOutputSizeForFinal in class OpenSSLAeadCipher
