# DigestAlgorithm

`interface DigestAlgorithm`

Interface for injecting custom digest implementation bypassing JCA.

### Properties

#### algorithm | Algorithm identifier. `abstract val algorithm: String`
#### digestLength | The length of the digest in bytes. `abstract val digestLength: Int`

### Functions

#### componentDigest | 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. `open fun componentDigest(bytes: ByteArray): ByteArray`
#### digest | Computes the digest of the ByteArray. `abstract fun digest(bytes: ByteArray): ByteArray`
#### nonceDigest | 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. `open fun nonceDigest(bytes: ByteArray): ByteArray`
