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
• BIP340 Schnorr signature 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
