I have to pass a username to a webservice, and the API is asking for the following.
1: The username has to be encrypted with AES
2: The AES output has to be converted to BASE16
3: It is the BASE16 value I have to pass.
The encryption is easy - but I cannot find a way to convert the value to BASE16.
PHP does not seem to have a BASE16_ENCODE like it does for BASE64.
$value = <AES Encrypted Username>;
$base16username = base16_encode('$value'); (< Since Base16_encode does not exist, this is my problem)
Google searches are leading me nowhere, nor is the PHP online manual so I suspect I might be overlooking something obvious.
