OpenSSL is a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. Its superpower is the ability to automatically detect the encoding standard. Whether you're using Linux, Windows or macOS you can use built-in tools to both encode or decode Base64 data. This will output a very long, base64 encoded string. Just base64 encode a binary file: openssl base64 -in file. The library is developed as open source and can be used on multiple operating systems. txt To get this back into openssl parsable output, use the base64 -d command: base64 -d sign. This was because openssl does no 'pure' base64 encoding by default but uses the pem standard base64 encoding scheme ( this is why adding the lines from roxas will make it work in the most cases because the newlines are ignored ) but if you want to decode base64 that is used inside a certificate or. Code presented here is both binary safe, and portable (i. OpenSSL v1. OpenSSL on Windows is a bit trickier as you need to install a pre-compiled binary to get started.
