How we make sure

    
We check this tool with the automated test suites linked below. Example checks are shown in their original language.

    

        

            
Verification method

            
Check the RFC4648 foo vector, binary-byte round trips and invalid alphabet rejection. Decoder regressions cover retained Hex/Base64 source selectors and uploaded encoded text.

        

        

            
Comparison reference

            
RFC 4648 section 10 fixed foo → MZXW6=== vector; same @scure/base 2.0.0 inverse for binary cases.

These checks cover the listed examples and boundaries, not every possible input. Round trips and checks using the same library are not independent verification.
