DESCRIPTION
Provides an interface to the CHAES digest algorithm.

FUNCTIONS
chaes
Logically joins all arguments into a single string, and returns its CHAES digest encoded as a binary string.
$chaes_raw = chaes( 'data string' );
$chaes_raw = chaes( 'any data' , 'more data' , 'even more data' );
|
chaes_hex
Logically joins all arguments into a single string, and returns its CHAES digest encoded as a hexadecimal string.
$chaes_hex = chaes_hex( 'data string' );
$chaes_hex = chaes_hex( 'any data' , 'more data' , 'even more data' );
|
chaes_b64
Logically joins all arguments into a single string, and returns its CHAES digest encoded as a Base64 string, with trailing '=' padding.
$chaes_b64 = chaes_b64( 'data string' );
$chaes_b64 = chaes_b64( 'any data' , 'more data' , 'even more data' );
|
chaes_b64u
Logically joins all arguments into a single string, and returns its CHAES digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$chaes_b64url = chaes_b64u( 'data string' );
$chaes_b64url = chaes_b64u( 'any data' , 'more data' , 'even more data' );
|
chaes_file
Reads file (defined by filename or filehandle) content, and returns its CHAES digest encoded as a binary string.
$chaes_raw = chaes_file( 'filename.dat' );
$chaes_raw = chaes_file( *FILEHANDLE );
|
chaes_file_hex
Reads file (defined by filename or filehandle) content, and returns its CHAES digest encoded as a hexadecimal string.
$chaes_hex = chaes_file_hex( 'filename.dat' );
$chaes_hex = chaes_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.
chaes_file_b64
Reads file (defined by filename or filehandle) content, and returns its CHAES digest encoded as a Base64 string, with trailing '=' padding.
$chaes_b64 = chaes_file_b64( 'filename.dat' );
$chaes_b64 = chaes_file_b64( *FILEHANDLE );
|
chaes_file_b64u
Reads file (defined by filename or filehandle) content, and returns its CHAES digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$chaes_b64url = chaes_file_b64u( 'filename.dat' );
$chaes_b64url = chaes_file_b64u( *FILEHANDLE );
