SymmetricKeyAlgorithmPolicy

public SymmetricKeyAlgorithmPolicy(SymmetricKeyAlgorithm defaultSymmetricKeyAlgorithm,
                                   java.util.List<SymmetricKeyAlgorithm> acceptableSymmetricKeyAlgorithms)

Method Detail

getDefaultSymmetricKeyAlgorithm

public SymmetricKeyAlgorithm getDefaultSymmetricKeyAlgorithm()

Return the default symmetric key algorithm. This algorithm is used as a fallback when no consensus about symmetric algorithms can be reached.

Returns:

default symmetric encryption algorithm

isAcceptable

public boolean isAcceptable(SymmetricKeyAlgorithm algorithm)

Return true if the given symmetric encryption algorithm is acceptable by this policy.

Parameters:

algorithm - algorithm

Returns:

true if algorithm is acceptable, false otherwise

isAcceptable

public boolean isAcceptable(int algorithmId)

Return true if the given symmetric encryption algorithm is acceptable by this policy.

Parameters:

algorithmId - algorithm

Returns:

true if algorithm is acceptable, false otherwise

defaultSymmetricKeyEncryptionAlgorithmPolicy

public static Policy.SymmetricKeyAlgorithmPolicy defaultSymmetricKeyEncryptionAlgorithmPolicy()

The default symmetric encryption algorithm policy of PGPainless.

Returns:

default symmetric encryption algorithm policy

defaultSymmetricKeyDecryptionAlgorithmPolicy

public static Policy.SymmetricKeyAlgorithmPolicy defaultSymmetricKeyDecryptionAlgorithmPolicy()

The default symmetric decryption algorithm policy of PGPainless.

Returns:

default symmetric decryption algorithm policy

selectBest

public SymmetricKeyAlgorithm selectBest(java.util.List<SymmetricKeyAlgorithm> options)

Select the best acceptable algorithm from the options list. The best algorithm is the first algorithm we encounter in our list of acceptable algorithms that is also contained in the list of options.

Parameters:

options - list of algorithm options

Returns:

best
