node.js 6.0.0 buffer to string equivalent in python3

Question

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

this lib is use in a node 6.0.0 environment

I did take a look at this node issue, but i don't understand if it's linked to my problem.

js function:

const KDF_PARTY_V = Buffer.from('E6F8C08930597B47472620568D207A23E4FCEF4B3F0AA3DC26FF369C622C6E1D', 'hex').toString('binary') 
// The SHA-256 hash of your ID string literal; 32 bytes in size.
console.log(KDF_PARTY_V)

output:

æøÀ0Y{GG& V z#äüïK?
£Ü&ÿ6b,n

python equivalent:

kdf_v = memoryview(bytes.fromhex('E6F8C08930597B47472620568D207A23E4FCEF4B3F0AA3DC26FF369C622C6E1D')).tobytes().decode('latin-1')
print(kdf_v)

the output (badly shown by stack)

æøÀ‰0Y{GG& V z#äüïK?
£Ü&ÿ6œb,n

My actual console message: maybe i sould use something different than latin-1 and utf-8 ?

Answer 1

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
