Method Details

getBotanCipherName

protected String getBotanCipherName(int keyLength)

Description copied from class: BotanBaseAsymmetricCipher

Gets the native botan cipher name (e.g. 'AES-128/CBC/PKCS7').

Specified by:

getBotanCipherName in class BotanBaseAsymmetricCipher

Parameters:

keyLength - the key length

Returns:

String containing the Botan cipher name.

isValidNonceLength

protected boolean isValidNonceLength(int nonceLength)

Description copied from class: BotanBaseAsymmetricCipher

Checks whether the given nonce size is supported.

Specified by:

isValidNonceLength in class BotanBaseAsymmetricCipher

Parameters:

nonceLength - the nonce length

Returns:

True is the given nonce length is supported, False otherwise.
