PyCryptodome is a self-contained Python package of low-level cryptographic primitives, forked from PyCrypto with an almost drop-in compatible API. It implements symmetric ciphers, authenticated encryption modes, hashes, MACs, key derivation, and asymmetric cryptography in C extensions without wrapping an external crypto library.
Use cases
- encrypt and decrypt data with AES in Python
- generate RSA or ECC key pairs
- sign and verify digital signatures
- compute SHA-3 or BLAKE2 hashes
- replace the old PyCrypto library
- do authenticated encryption with GCM or ChaCha20-Poly1305
- derive keys with PBKDF2 or scrypt
- implement HPKE encryption
When to choose
- you need low-level cryptographic primitives in Python with no external C library dependency
- you are migrating legacy code from PyCrypto
- you need modern algorithms like Ed25519, XChaCha20, SHA-3, or HPKE
- you need PyPy support for crypto workloads
When to avoid
- you want a high-level, misuse-resistant API rather than raw primitives
- you prefer a library wrapping OpenSSL like pyca/cryptography
- you need FIPS-validated cryptography
