Frequently Asked Questions
Base64 encoding is designed to safely transmit binary data or special characters over text-based protocols (such as JSON, XML, or email MIME) that might otherwise corrupt raw binary or control bytes.
No. Base64 is an encoding format, not an encryption algorithm. Anyone can decode Base64 back into its original form without a secret key. Never use Base64 alone to secure sensitive data.
Decoding errors usually occur when the input is not valid Base64 (contains invalid characters, missing padding =, or resolving to invalid multi-byte character sequences). Check the character set switch if decoding international text.
