node.js 6.0.0 buffer to string equivalent in python3-CodePudding

I'm converting an old node.js lib into python and can't reproduce the behaviour of Buffer.toString() in python.

maybe i sould use something different than latin-1 and utf-8 ?

CodePudding user response：

Just don't try to decode at all. Decoding turns bytestrings into text strings, and a hash isn't a text string.

kdf_v = bytes.fromhex('E6F8C08930597B47472620568D207A23E4FCEF4B3F0AA3DC26FF369C622C6E1D')

gives you a 32-byte bytes object, which is functionally equivalent to a Node.js Buffer.

CodePudding user response：

it was just a console caracter encoding mistake

when looking at the binary data itself the python version is the same as the js one so:

kdf_v = bytes.fromhex(merchant_id).decode('latin1')

work perfectly

@AKX i do need to have the variable in str format, because i use it in a concatenation and the result of it in a sha256 digest
