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
