To convert base 64 data: It's analogous to the binary conversion.
Base64 is a binary-to-text encoding scheme, it encodes binary data in plain text.
Base64 allows to transmit the data without loss or modification of the contents. It is useful for protocols that expect ASCII data.
Base64 represents binary data in an ASCII string format.
A 65-character subset of US-ASCII is used. Each digit represents exactly 6 bits of data (2^6=64).
Base 64 Alphabet: a-zA-Z0-9+/
The extra 65th character "=" is used to signify a special processing function.
Base64 encoding is not a way of encrypting!
