NAME
Crypt::Digest::RIPEMD128 - Hash function RIPEMD-128 [size: 128 bits]
SYNOPSIS
### Functional interface: use Crypt::Digest::RIPEMD128 qw( ripemd128 ripemd128_hex ripemd128_b64 ripemd128_b64u ripemd128_file ripemd128_file_hex ripemd128_file_b64 ripemd128_file_b64u ); # calculate digest from string/buffer $ripemd128_raw = ripemd128('data string'); $ripemd128_hex = ripemd128_hex('data string'); $ripemd128_b64 = ripemd128_b64('data string'); $ripemd128_b64u = ripemd128_b64u('data string'); # calculate digest from file $ripemd128_raw = ripemd128_file('filename.dat'); $ripemd128_hex = ripemd128_file_hex('filename.dat'); $ripemd128_b64 = ripemd128_file_b64('filename.dat'); $ripemd128_b64u = ripemd128_file_b64u('filename.dat'); # calculate digest from filehandle $ripemd128_raw = ripemd128_file(*FILEHANDLE); $ripemd128_hex = ripemd128_file_hex(*FILEHANDLE); $ripemd128_b64 = ripemd128_file_b64(*FILEHANDLE); $ripemd128_b64u = ripemd128_file_b64u(*FILEHANDLE); ### OO interface: use Crypt::Digest::RIPEMD128; $d = Crypt::Digest::RIPEMD128->new; $d->add('any data'); $d->addfile('filename.dat'); $d->addfile(*FILEHANDLE); $result_raw = $d->digest; # raw bytes $result_hex = $d->hexdigest; # hexadecimal form $result_b64 = $d->b64digest; # Base64 form $result_b64u = $d->b64udigest; # Base64 URL Safe form
DESCRIPTION
Provides an interface to the RIPEMD128 digest algorithm.
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 Logically joins all arguments into a single string, and returns its RIPEMD128 digest encoded as a binary string. $ripemd128_raw = ripemd128('data string'); #or $ripemd128_raw = ripemd128('any data', 'more data', 'even more data'); ripemd128_hex Logically joins all arguments into a single string, and returns its RIPEMD128 digest encoded as a hexadecimal string. $ripemd128_hex = ripemd128_hex('data string'); #or $ripemd128_hex = ripemd128_hex('any data', 'more data', 'even more data'); ripemd128_b64 Logically joins all arguments into a single string, and returns its RIPEMD128 digest encoded as a Base64 string, with trailing '=' padding. $ripemd128_b64 = ripemd128_b64('data string'); #or $ripemd128_b64 = ripemd128_b64('any data', 'more data', 'even more data'); ripemd128_b64u Logically joins all arguments into a single string, and returns its RIPEMD128 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5). $ripemd128_b64url = ripemd128_b64u('data string'); #or $ripemd128_b64url = ripemd128_b64u('any data', 'more data', 'even more data'); ripemd128_file Reads file (defined by filename or filehandle) content, and returns its RIPEMD128 digest encoded as a binary string. $ripemd128_raw = ripemd128_file('filename.dat'); #or $ripemd128_raw = ripemd128_file(*FILEHANDLE); ripemd128_file_hex Reads file (defined by filename or filehandle) content, and returns its RIPEMD128 digest encoded as a hexadecimal string. $ripemd128_hex = ripemd128_file_hex('filename.dat'); #or $ripemd128_hex = ripemd128_file_hex(*FILEHANDLE); BEWARE: You have to make sure that the filehandle is in binary mode before you pass it as argument to the addfile() method. ripemd128_file_b64 Reads file (defined by filename or filehandle) content, and returns its RIPEMD128 digest encoded as a Base64 string, with trailing '=' padding. $ripemd128_b64 = ripemd128_file_b64('filename.dat'); #or $ripemd128_b64 = ripemd128_file_b64(*FILEHANDLE); ripemd128_file_b64u Reads file (defined by filename or filehandle) content, and returns its RIPEMD128 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5). $ripemd128_b64url = ripemd128_file_b64u('filename.dat'); #or $ripemd128_b64url = ripemd128_file_b64u(*FILEHANDLE);
METHODS
The OO interface provides the same set of functions as Crypt::Digest. new $d = Crypt::Digest::RIPEMD128->new(); clone $d->clone(); reset $d->reset(); add $d->add('any data'); #or $d->add('any data', 'more data', 'even more data'); addfile $d->addfile('filename.dat'); #or $d->addfile(*FILEHANDLE); add_bits $d->add_bits($bit_string); # e.g. $d->add_bits("111100001010"); #or $d->add_bits($data, $nbits); # e.g. $d->add_bits("\xF0\xA0", 16); hashsize $d->hashsize; #or Crypt::Digest::RIPEMD128->hashsize(); #or Crypt::Digest::RIPEMD128::hashsize(); digest $result_raw = $d->digest(); hexdigest $result_hex = $d->hexdigest(); b64digest $result_b64 = $d->b64digest(); b64udigest $result_b64url = $d->b64udigest();
