DESCRIPTION
Provides an interface to the MD2 digest algorithm.
EXPORT
Nothing is exported by default.
You can export selected functions:
md2_file md2_file_hex md2_file_b64 md2_file_b64u) ;

Or all of them at once:
FUNCTIONS
md2
Logically joins all arguments into a single string, and returns its MD2 digest encoded as a binary string.
$md2_raw = md2( 'data string' );
$md2_raw = md2( 'any data' , 'more data' , 'even more data' );
|
md2_hex
Logically joins all arguments into a single string, and returns its MD2 digest encoded as a hexadecimal string.
$md2_hex = md2_hex( 'data string' );
$md2_hex = md2_hex( 'any data' , 'more data' , 'even more data' );
|
md2_b64
Logically joins all arguments into a single string, and returns its MD2 digest encoded as a Base64 string, with trailing '=' padding.
$md2_b64 = md2_b64( 'data string' );
$md2_b64 = md2_b64( 'any data' , 'more data' , 'even more data' );
|
md2_b64u
Logically joins all arguments into a single string, and returns its MD2 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$md2_b64url = md2_b64u( 'data string' );
$md2_b64url = md2_b64u( 'any data' , 'more data' , 'even more data' );
|
md2_file
Reads file (defined by filename or filehandle) content, and returns its MD2 digest encoded as a binary string.
$md2_raw = md2_file( 'filename.dat' );
$md2_raw = md2_file( *FILEHANDLE );
|
md2_file_hex
Reads file (defined by filename or filehandle) content, and returns its MD2 digest encoded as a hexadecimal string.
$md2_hex = md2_file_hex( 'filename.dat' );
$md2_hex = md2_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.
md2_file_b64
Reads file (defined by filename or filehandle) content, and returns its MD2 digest encoded as a Base64 string, with trailing '=' padding.
$md2_b64 = md2_file_b64( 'filename.dat' );
$md2_b64 = md2_file_b64( *FILEHANDLE );
|
md2_file_b64u
Reads file (defined by filename or filehandle) content, and returns its MD2 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$md2_b64url = md2_file_b64u( 'filename.dat' );
$md2_b64url = md2_file_b64u( *FILEHANDLE );
