Questions about the Base64 Encoder / Decoder
Base64 is a way of writing any data using only letters, digits, and a few symbols, so it can travel safely through systems built for plain text, such as email and web addresses.
Choose Decode, paste the Base64 text, and choose Decode Base64. The result appears as text. If the data is not valid Base64, or does not decode to text, the tool says so.
Base64 is an encoding, not encryption. Anyone can decode it, so never use it to protect a secret.
