[8] yaSSL offered a more modern API, commercial style developer support and was complete with an OpenSSL compatibility layer.

[13] wolfCrypt Provides RSA, ECC, DSS, Diffie–Hellman, EDH, NTRU (deprecated and removed), DES, Triple DES, AES (CBC, CTR, CCM, GCM), Camellia, IDEA, ARC4, HC-128, ChaCha20, MD2, MD4, MD5, SHA-1, SHA-2, SHA-3, BLAKE2, RIPEMD-160, Poly1305, Random Number Generation, Large Integer support, base 16/64 encoding/decoding, and post-quantum cryptographic algorithms: ML-KEM (certified under FIPS 203) and ML-DSA (certified under FIPS 204).

wolfCrypt acts as a back-end crypto implementation for several popular software packages and libraries, including MIT Kerberos[14] (where it can be enabled using a build option).

[15] NTRU works well in mobile and embedded environments due to the reduced bit size needed to provide the same security as other public key systems.
