|
Heavily optimized cryptography algorithms for embedded devices.
|
|
|
|
These include:
|
|
- AES/Rijndael encryption/decryption
|
|
- Big Number (256 bit) Arithmetics
|
|
- BIP32 Hierarchical Deterministic Wallets
|
|
- BIP39 Mnemonic code
|
|
- ECDSA signing/verifying (supports secp256k1 and nist256p1 curves,
|
|
uses RFC6979 for deterministic signatures)
|
|
- ECDSA public key derivation
|
|
- Schnorr (BCH variant) signing/verifying
|
|
- Base32 (RFC4648 and custom alphabets)
|
|
- Base58 address representation
|
|
- Ed25519 signing/verifying (also SHA3 and Keccak variants)
|
|
- ECDH using secp256k1, nist256p1 and Curve25519
|
|
- HMAC-SHA256 and HMAC-SHA512
|
|
- PBKDF2
|
|
- RIPEMD-160
|
|
- SHA1
|
|
- SHA2-256/SHA2-512
|
|
- SHA3/Keccak
|
|
- BLAKE2s/BLAKE2b
|
|
- Chacha20-Poly1305
|
|
- unit tests (using Check - check.sf.net; in test_check.c)
|
|
- tests against OpenSSL (in test_openssl.c)
|
|
- integrated Wycheproof tests
