Basic Auth Decoder

Calculates the plaintext credentials encoded within an HTTP Basic Authorization header. The tool accepts a Base64 string, which represents a username and password combination separated by a colon. By decoding this standard encoding format, it reveals the original, readable account details that were used to generate the header. This process is necessary because Basic Authentication transmits user credentials in an obfuscated form rather than their true text representation. Security researchers and developers use this tool when analyzing network traffic or examining API call logs. It allows users to quickly inspect captured headers to verify authentication data without needing specialized decoding software. By converting the Base64 string back into its original components, it helps confirm the specific identity credentials associated with a given service endpoint.
