I am trying to get a working and good version of base64 conversions using OpenSSL. Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. Here is an example of OpenSSL base64 encode/decode I wrote: Notice, I have some macros/classes in the code that I wrote, but none of them is important for the example. If you want base-64 encoding use -inform/-outform P to get PKCS7 encapsulation. It permits encrypting/decrypting files, as well as generating RSA keys, encrypting private RSA keys, signing files using an RSA key, and also verifying signatures using RSA. It is an open-source implementation tool for SSL/TLS and is used on about 65% of all active internet servers, making it the unofficial industry standard. # openssl enc -aes-128-cbc -d -in file. OpenSSL is a cryptography toolkit implementing the Secure Sockets Layer ( SSL v2/v3) and Transport Layer Security ( TLS v1) network protocols and related cryptography standards required by them.
