NAMECrypt::Mac::XCBC - Message authentication code XCBC (RFC 3566) SYNOPSIS### Functional interface: use Crypt::Mac::XCBC qw( xcbc xcbc_hex ); # calculate MAC from string/buffer $xcbc_raw = xcbc($cipher_name, $key, 'data buffer'); $xcbc_hex = xcbc_hex($cipher_name, $key, 'data buffer'); $xcbc_b64 = xcbc_b64($cipher_name, $key, 'data buffer'); $xcbc_b64u = xcbc_b64u($cipher_name, $key, 'data buffer'); ### OO interface: use Crypt::Mac::XCBC; $d = Crypt::Mac::XCBC->new($cipher_name, $key); $d->add('any data'); $d->addfile('filename.dat'); $d->addfile(*FILEHANDLE); $result_raw = $d->mac; # raw bytes $result_hex = $d->hexmac; # hexadecimal form $result_b64 = $d->b64mac; # Base64 form $result_b64u = $d->b64umac; # Base64 URL Safe form DESCRIPTIONProvides an interface to the XCBC message authentication code (MAC) algorithm. EXPORTNothing is exported by default. You can export selected functions: use Crypt::Mac::XCBC qw(xcbc xcbc_hex ); Or all of them at once: use Crypt::Mac::XCBC ':all'; FUNCTIONSxcbcLogically joins all arguments into a single string, and returns its XCBC message authentication code encoded as a binary string. $xcbc_raw = xcbc($cipher_name, $key, 'data buffer'); #or $xcbc_raw = xcbc($cipher_name, $key, 'any data', 'more data', 'even more data'); xcbc_hexLogically joins all arguments into a single string, and returns its XCBC message authentication code encoded as a hexadecimal string. $xcbc_hex = xcbc_hex($cipher_name, $key, 'data buffer'); #or $xcbc_hex = xcbc_hex($cipher_name, $key, 'any data', 'more data', 'even more data'); xcbc_b64Logically joins all arguments into a single string, and returns its XCBC message authentication code encoded as a Base64 string. $xcbc_b64 = xcbc_b64($cipher_name, $key, 'data buffer'); #or $xcbc_b64 = xcbc_b64($cipher_name, $key, 'any data', 'more data', 'even more data'); xcbc_b64uLogically joins all arguments into a single string, and returns its XCBC message authentication code encoded as a Base64 URL Safe string (see RFC 4648 section 5). $xcbc_b64url = xcbc_b64u($cipher_name, $key, 'data buffer'); #or $xcbc_b64url = xcbc_b64u($cipher_name, $key, 'any data', 'more data', 'even more data'); METHODSnew$d = Crypt::Mac::XCBC->new($cipher_name, $key); clone$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 $d->addfile(*FILEHANDLE); mac$result_raw = $d->mac(); hexmac$result_hex = $d->hexmac(); b64mac$result_b64 = $d->b64mac(); b64umac$result_b64url = $d->b64umac(); SEE ALSO
