crypto_cpp_py

✓ import crypto_cpp_py

✗ import crypto_cpp

Compute a single Pedersen hash.

import crypto_cpp # Compute a Pedersen hash result = crypto_cpp.pedersen_hash(b"hello") print(result.hex())

Debug

Known issues

breakingIn v2.0.0, the pedersen_hash function now returns bytes instead of a hex string.

fix

Use .hex() on the result if you need a string.

affects: >=2.0.0 <3.0.0

deprecatedFunctions prefixed with '_' (e.g., '_crypto_cpp_init') are internal and may be removed in v3.0.0.

fix

Do not call underscored functions; use public API.

affects: >=2.0.0

gotchaThe library expects bytes inputs; passing a string will cause a TypeError.

fix

Always encode strings: b"data" or .encode()

affects: >=1.0.0
