Result
Encodes text into Base64 or decodes Base64 back into plain text, and generates SHA-1, SHA-256 and SHA-512 cryptographic hashes of any input.
Good to know: Base64 is an encoding (reversible, not secret), while SHA hashes are one-way — you can't get the original text back from a hash. Don't confuse the two: Base64 is for safely transporting data, hashing is for verifying integrity or storing passwords.
