Display Help:

b64 --help

Encode a ASCII text as base 64 ASCII text:

b64 encode Hello
b64 encode -f hello.txt
b64 encode < hello.txt
cat hello.txt | b64 encode

Decode a base64 ASCII text to regular ASCII text:

b64 decode SGVsbG8=
b64 decode -f hello.txt
b64 decode < hello.txt
cat hello.txt | b64 decode
