Base64 Decode

Base64 Decode is a way to decode ASCII string format to binary. This encoding/decoding scheme is used when binary data needs to be stored and transferred over media.

Why Base64 Encoding/Decoding is Required?

The dependence for Base64 encoding comes from the problems that occur subsequent to media is transmitted in raw binary format to text-based systems.

Since text-based systems (subsequent to email) add footnotes to binary data as a broad range of characters, including special command characters, much of the binary data that is transmitted to transfer media is misinterpreted by those systems and lost or corrupted in the transmission process.

One method of encoding this allowable of binary data in a pretentiousness that avoids such transmission problems is to send it as plain ASCII text in Base64 encoded format. This is one of the techniques employed by the MIME going on to all right to send data another than plain text.
