module RbNaCl::Hash

def self.blake2b(data, options = {})

Returns:
  • (String) - The Blake2b hash digest as raw bytes

Raises:
  • (CryptoError) - If the hashing fails for some reason.

Options Hash: (**options)
  • personal (Personal) -- Provide personalisation string to allow pinning a hash for a particular purpose.
  • salt (String) -- Provide a salt to support randomised hashing.
  • key (String) -- 64-byte (or less) key for keyed mode
  • digest_size (Fixnum) -- Size in bytes (1-64, default 64)

Parameters:
  • data (String) -- The data, as a collection of bytes 
def self.blake2b(data, options = {})
  Blake2b.digest(data, options)
end

def self.sha256(data)

Returns:
  • (String) - The SHA-256 hash digest as raw bytes

Raises:
  • (CryptoError) - If the hashing fails for some reason.

Parameters:
  • data (#to_str) -- The data, as a collection of bytes 
def self.sha256(data)
  data   = data.to_str
  digest = Util.zeros(SHA256::BYTES)
  SHA256.hash_sha256(digest, data, data.bytesize) || raise(CryptoError, "Hashing failed!")
  digest
end

def self.sha512(data)

Returns:
  • (String) - The SHA-512 hash digest as raw bytes

Raises:
  • (CryptoError) - If the hashing fails for some reason.

Parameters:
  • data (#to_str) -- The data, as a collection of bytes 
def self.sha512(data)
  digest = Util.zeros(SHA512::BYTES)
  SHA512.hash_sha512(digest, data, data.bytesize) || raise(CryptoError, "Hashing failed!")
  digest
end
