Frequently Asked Questions (FAQ)
Q: Why does it say decoding failed?
A: This is usually because the input is not a valid Base64 string, or the string is incomplete.
Q: Is Base64 decoding the same as decryption?
A: Strictly speaking, no. Base64 is an encoding conversion, not decryption in the cryptographic sense.
