library0.1.34pypypi✓ verified 82d ago

pysequoia is a Python binding for the Sequoia-PGP library, providing OpenPGP functionality such as encryption, decryption, signing, and verification. Version 0.1.34 requires Python 3.7+ and wraps Sequoia's low-level FFI with a Pythonic API. Release cadence is irregular, driven by upstream Sequoia changes.

✓ from pysequoia import decrypt

Generate an OpenPGP key pair using Sequoia-PGP via pysequoia.

import os from pysequoia import sequoia_openpgp as sop # Generate a key pair key = sop.generate_key(b'Alice <alice@example.org>') # Export public key public_key = sop.extract_public_key(key) print(public_key.decode())

Debug

Known issues

breakingThe pysequoia API is not stable; functions and arguments can change between minor versions without deprecation. Pin the exact version in requirements.

fix

Use 'pysequoia==0.1.34' in your requirements.txt.

affects: all

gotchaAll cryptographic operations (encrypt, decrypt, sign, verify) return bytes, not strings. Attempting to use them as strings may cause unexpected behavior.

fix

Decode bytes to a string if necessary: result = sop.encrypt(...).decode('utf-8').

affects: all

gotchaThe library relies on Sequoia-PGP's system-installed binary; on some platforms (e.g., Alpine Linux) the shared library may not be found, leading to an ImportError.

fix

Ensure the Sequoia-PGP system package (libsequoia-openpgp) is installed. On Debian/Ubuntu: apt install libsequoia-openpgp-ffi-dev.

affects: all

deprecatedFunction 'generate_key' has been renamed to 'generate_key_pair' in the development branch. The old name will be removed in a future release.

fix

Use 'generate_key_pair' instead of 'generate_key'.

affects: <=0.1.34

breakingThe module name 'sequoia_openpgp' (the high-level wrapper) may be broken out into a separate package in future. Imports from 'pysequoia.sequoia_openpgp' may change.

fix

Monitor the repository for announcements about import path changes.

affects: future
