EXPORT
Nothing is exported by default.
You can export selected functions:
use Crypt::Digest::RIPEMD128 qw(ripemd128 ripemd128_hex ripemd128_b64 ripemd128_b64u
ripemd128_file ripemd128_file_hex ripemd128_file_b64 ripemd128_file_b64u);Or all of them at once:
use Crypt::Digest::RIPEMD128 ':all';FUNCTIONS
ripemd128
Joins all arguments into a single string and returns its RIPEMD128 digest encoded as a binary string.
Data arguments for the functional helpers are converted to byte strings using Perl's usual scalar stringification. Defined scalars, including numbers and string-overloaded objects, are accepted. undef is treated as an empty string and may emit Perl's usual "uninitialized value" warning. The same rules apply to ripemd128_hex, ripemd128_b64, and ripemd128_b64u.
my $ripemd128_raw = ripemd128('data string');
#or
my $ripemd128_raw = ripemd128('any data', 'more data', 'even more data');ripemd128_hex
Joins all arguments into a single string and returns its RIPEMD128 digest encoded as a hexadecimal string.
my $ripemd128_hex = ripemd128_hex('data string');
#or
my $ripemd128_hex = ripemd128_hex('any data', 'more data', 'even more data');ripemd128_b64
Joins all arguments into a single string and returns its RIPEMD128 digest encoded as a Base64 string, with trailing '=' padding.
my $ripemd128_b64 = ripemd128_b64('data string');
#or
my $ripemd128_b64 = ripemd128_b64('any data', 'more data', 'even more data');ripemd128_b64u
Joins all arguments into a single string and returns its RIPEMD128 digest encoded as a Base64 URL-safe string (see RFC 4648 section 5).
my $ripemd128_b64url = ripemd128_b64u('data string');
#or
my $ripemd128_b64url = ripemd128_b64u('any data', 'more data', 'even more data');ripemd128_file
Reads a file given by a filename or filehandle and returns its RIPEMD128 digest encoded as a binary string.
my $ripemd128_raw = ripemd128_file('filename.dat');
#or
my $filehandle = ...; # existing binary-mode filehandle
my $ripemd128_raw = ripemd128_file($filehandle);ripemd128_file_hex
Reads a file given by a filename or filehandle and returns its RIPEMD128 digest encoded as a hexadecimal string.
my $ripemd128_hex = ripemd128_file_hex('filename.dat');
#or
my $filehandle = ...; # existing binary-mode filehandle
my $ripemd128_hex = ripemd128_file_hex($filehandle);Note: The filehandle must be in binary mode before you pass it to addfile().
ripemd128_file_b64
Reads a file given by a filename or filehandle and returns its RIPEMD128 digest encoded as a Base64 string, with trailing '=' padding.
my $ripemd128_b64 = ripemd128_file_b64('filename.dat');
#or
my $filehandle = ...; # existing binary-mode filehandle
my $ripemd128_b64 = ripemd128_file_b64($filehandle);ripemd128_file_b64u
Reads a file given by a filename or filehandle and returns its RIPEMD128 digest encoded as a Base64 URL-safe string (see RFC 4648 section 5).
my $ripemd128_b64url = ripemd128_file_b64u('filename.dat');
#or
my $filehandle = ...; # existing binary-mode filehandle
my $ripemd128_b64url = ripemd128_file_b64u($filehandle);METHODS
The OO interface provides the same set of functions as Crypt::Digest. Unless noted otherwise, assume $d is an existing digest object created via new, for example:
my $d = Crypt::Digest::RIPEMD128->new();new
my $d = Crypt::Digest::RIPEMD128->new();clone
$d->clone();reset
$d->reset();add
Appends data to the message. Returns the object itself (for chaining).
Each argument is converted to bytes using Perl's usual scalar stringification. Defined scalars, including numbers and string-overloaded objects, are accepted. undef is treated as an empty string and may emit Perl's usual "uninitialized value" warning.
$d->add('any data');
#or
$d->add('any data', 'more data', 'even more data');addfile
Reads the file content and appends it to the message. Returns the object itself (for chaining).
$d->addfile('filename.dat');
#or
my $filehandle = ...; # existing binary-mode filehandle
$d->addfile($filehandle);hashsize
$d->hashsize;
#or
Crypt::Digest::RIPEMD128->hashsize();
#or
Crypt::Digest::RIPEMD128::hashsize();digest
Returns the binary digest (raw bytes). The first call finalizes the digest object. Any later add(), addfile(), digest(), hexdigest(), b64digest(), or b64udigest() call will fail until you call reset().
my $result_raw = $d->digest();hexdigest
Returns the digest encoded as a lowercase hexadecimal string. Like digest(), the first call finalizes the digest object.
my $result_hex = $d->hexdigest();b64digest
Returns the digest encoded as a Base64 string with trailing = padding. Like digest(), the first call finalizes the digest object.
my $result_b64 = $d->b64digest();b64udigest
Returns the digest encoded as a Base64 URL-safe string (no trailing =). Like digest(), the first call finalizes the digest object.
my $result_b64url = $d->b64udigest();
