Method Detail

getPreferredHashAlgorithms

public static List<HashAlgorithm> getPreferredHashAlgorithms(org.bouncycastle.openpgp.PGPPublicKey publicKey)

guessPreferredHashAlgorithms

public static List<HashAlgorithm> guessPreferredHashAlgorithms(org.bouncycastle.openpgp.PGPPublicKey publicKey)

Return the hash algorithm that was used in the latest self signature.

Parameters:

publicKey - public key

Returns:

list of hash algorithm

getOrGuessPreferredHashAlgorithms

public static Set<HashAlgorithm> getOrGuessPreferredHashAlgorithms(org.bouncycastle.openpgp.PGPPublicKey publicKey)

Try to extract hash algorithm preferences from self signatures. If no self-signature containing hash algorithm preferences is found, try to derive a hash algorithm preference by inspecting the hash algorithm used by existing self-signatures.

Parameters:

publicKey - key

Returns:

hash algorithm preferences (might be empty!)
