Interface DigestAlgorithm

public DigestAlgorithm

Interface for injecting custom digest implementation bypassing JCA.

Constructor Detail

DigestAlgorithm

public DigestAlgorithm()

Method Detail

getAlgorithm

@NotNull
java.lang.String getAlgorithm()

Algorithm identifier.

getDigestLength

int getDigestLength()

The length of the digest in bytes.

digest

@NotNull
kotlin.Array[] digest(@NotNull
                               kotlin.Array[] bytes)

Computes the digest of the ByteArray.

Parameters:

bytes - The ByteArray to hash.

componentDigest

@NotNull
kotlin.Array[] componentDigest(@NotNull
                                        kotlin.Array[] bytes)

Computes the digest of the ByteArray which is resistant to pre-image attacks. Only used to calculate the hash of the leaves of the ComponentGroup Merkle tree, starting from its serialized components. Default implementation provides double hashing, but can it be changed to single hashing or something else for better performance.

nonceDigest

@NotNull
kotlin.Array[] nonceDigest(@NotNull
                                    kotlin.Array[] bytes)

Computes the digest of the ByteArray which is resistant to pre-image attacks. Only used to calculate the nonces for the leaves of the ComponentGroup Merkle tree. Default implementation provides double hashing, but can it be changed to single hashing or something else for better performance.
