How Base64 Decoding Works
Base64 decoding reverses the encoding process. It takes the Base64 string (which uses 64 characters: A-Z, a-z, 0-9, +, /) and converts it back into the original binary data or text.
Common Uses
- Debugging: Inspecting encoded data in logs or APIs.
- Data Recovery: Extracting information from data URIs.
- Security Analysis: Decoding obfuscated strings in malware or scripts.
Example
Base64: SGVsbG8gV29ybGQ=
Text: "Hello World"
