hash_sha256 = Hash.sha256 message
hash_sha512 = Hash.sha512 signed

This is crypto_hash_* from NaCl.

type HashSha256 a = SizedByteArray CRYPTO_HASH_SHA256_BYTES a

Hash returned by sha256.

This type is parametrised by the actual data type that contains bytes. This can be, for example, a ByteString.

sha256

Arguments

:: (ByteArrayAccess pt, ByteArray hashBytes)

=> pt

Message to hash

-> HashSha256 hashBytes

hash = Hash.sha256 message

• message is the data you are hashing.

type HashSha512 a = SizedByteArray CRYPTO_HASH_SHA512_BYTES a

Hash returned by sha512.

This type is parametrised by the actual data type that contains bytes. This can be, for example, a ByteString.

sha512

Arguments

:: (ByteArrayAccess pt, ByteArray hashBytes)

=> pt

Message to hash

-> HashSha512 hashBytes

Hash a message using SHA-512.

hash = Hash.sha512 message
