Symmetric vs Asymmetric Cryptography

When it comes to the basics of cryptographic algorithms, one of the most fundamental distinctions is whether an algorithm is symmetric or asymmetric. Symmetric cryptography uses a single shared key for both encryption and decryption for example, AES. The operations are simple, and this makes symmetric algorithms fast and cheap, which is why it’s the […]

wolfEngine vs wolfProvider

At wolfSSL we provide two main services to help with the transition away from OpenSSL crypto operations, wolfEngine and wolfProvider. These both provide a plug and play solution to wolfSSL’s cryptography (which also can use our FIPS-140-3 module) in whatever application you may be using OpenSSL in. wolfEngine targets any application using OpenSSL 1.x using […]

wolfProvider Adds LMS Signature Verification

wolfSSL is adding verification-only LMS support to wolfProvider for OpenSSL applications. LMS is a stateful hash-based signature system standardized in RFC 8554 and NIST SP 800-208, making it useful for long-lived signing hierarchies and post-quantum verification. The integration accepts OpenSSL-compatible raw XDR public keys and uses wolfCrypt’s LMS verification APIs underneath the provider interface. What […]
