Digest::ECHO - Perl interface to the ECHO digest algorithm
# Functional interface use Digest::ECHO qw(echo_256 echo_256_hex echo_256_base64); $digest = echo_256($data); $digest = echo_256_hex($data); $digest = echo_256_base64($data); # Object-oriented interface use Digest::ECHO; $ctx = Digest::ECHO->new(256); $ctx->add($data); $ctx->addfile(*FILE); $digest = $ctx->digest; $digest = $ctx->hexdigest; $digest = $ctx->b64digest;
Digest::ECHO module provides an interface to the ECHO message digest algorithm. ECHO 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::ECHO module. None of these functions are exported by default.
Logically joins the arguments into a single string, and returns its ECHO digest encoded as a binary string.
Logically joins the arguments into a single string, and returns its ECHO digest encoded as a hexadecimal string.
Logically joins the arguments into a single string, and returns its ECHO digest encoded as a Base64 string, without any trailing padding.
The object-oriented interface to
Digest::ECHO is identical to that described by
Digest, except for the following:
$echo = Digest::ECHO->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.
