Digest::Keccak - Perl interface to the Keccak digest algorithm
# Functional interface use Digest::Keccak qw(keccak_256 keccak_256_hex keccak_256_base64); $digest = keccak_256($data); $digest = keccak_256_hex($data); $digest = keccak_256_base64($data); # Object-oriented interface use Digest::Keccak; $ctx = Digest::Keccak->new(256); $ctx->add($data); $ctx->addfile(*FILE); $digest = $ctx->digest; $digest = $ctx->hexdigest; $digest = $ctx->b64digest;
Digest::Keccak module provides an interface to the Keccak message digest algorithm. Keccak is a candidate in the NIST SHA-3 competition.
This interface follows the conventions set forth by the
The following functions are provided by the
Digest::Keccak module. None of these functions are exported by default.
Logically joins the arguments into a single string, and returns its Keccak digest encoded as a binary string.
Logically joins the arguments into a single string, and returns its Keccak digest encoded as a hexadecimal string.
Logically joins the arguments into a single string, and returns its Keccak digest encoded as a Base64 string, without any trailing padding.
The object-oriented interface to
Digest::Keccak is identical to that described by
Digest, except for the following:
$keccak = Digest::Keccak->new(256)
The constructor requires the algorithm to be specified. It must be one of: 224, 256, 384, 512.
Returns the algorithm used by the object.
