Many communication protocols like SMTP, NNTP were traditionally designed to work with plain text data represented by the 7-bit US-ASCII character set. Conversion from base64 text to bytes is called decoding. Here is the Ruby code that takes some text as input and converts it into Base-64 encoded string. Developers, on the other hand, can easily add this feature by utilizing external libraries. These operations include simple encoding like XOR or Base64, more complex encryption like AES, DES and Blowfish, creating binary and hexdumps, compression and decompression of data, calculating hashes and checksums, IPv6 and X. decode64(encoded) # "Ruby on Rails" Oct 8, 2017 · 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. g. Microsoft's Dotnet framework has support for encoding and decoding bytes to base64. "One case in which padding characters are required is concatenating multiple Base64 encoded files. To convert a string into Base64 encoding, at first echo the value and pipe the output into Base64 command.

Encryption is a technique used for protecting the confidentiality of the data. eg if you are using json in your applications but you need to process external messages that are using a different format. Note that, Base64 should not be confused with encryption or compression techniques. The encoding uses various algorithms to decrease the size of the file or the resource, whereas decoding is the process of reverting the encoded content of the file to its actual size. For many applications, this is sufficient encryption where the goal is simply to mangle any clear text sent over a wire, for example. Before we can convert a Unicode string to Base64 we need to decide on a binary encoding for that string.
