Is it possible to decode a base 64 string in linux or unix. If so, related commands or reference notes would be really helpful.
I am trying to encode and decode a String using android.util.Base64, but it gives a bad base-64 error.
Decode URL's, i.e. convert %HEX to the corresponding special characters, using only UNIX base utilities, and without having to type out each special character.
I have an anonymous C code snippet where the author assigns each hex digit a number from 0 to 16 and then does some bit shifting.
