BASE64 encoding/decoding using Terminal

To encode or decode standard input/output or any file content, Linux uses base64 encoding and decoding system.
Data are encoded and decoded to make the data transmission and storing process easier.
Encoding and decoding are not similar to encryption and decryption.
Encoded data can be easily revealed by decoding. So, this command-line utility tool can’t be used for data security. Alphabet, number and ‘=’ symbol are used to encode any data.
