Hi CJ101. I suspect something is trying to mess with the encoding of your binary data along the way. I would suggest using base64 encoding for the transmission and/or storage. Although it will make the data roughly 1/3 larger, it should eliminate your problems because all of the characters used by base64 are ASCII characters. [...]

Thanks for your feedback Snehamoy. I think you mean RSA_RC4 rather than PC4. I’m not sure if that relates just to RC4 encryption, or a combination of RSA asymmetric encryption and RC4 symmetrical encryption. If it’s just RC4 encryption, I don’t believe there is native support for it in PHP, but I did find a [...]

Python does not appear to have a direct equivalent function. The M2Crypto package can decode quite a few different formats, but openssl_seal() and openssl_open() aren’t included. Fortunately, M2Crypto contains the components required to decode this [...]
