wolfSSH With X.509 Support
wolfSSH can make use of X.509 certificates when verifying the peer! Both on the client side and on the server side. The implementation follows RFC 6187 and adds x509v3-ecdsa-sha2-* and x509v3-ssh-rsa to the key exchange algorithms. Instead of the public key, the whole certificate is passed along during authentication and then verified by the peer […]

Looking to add SSL/TLS to your Keil project? The wolfSSL embedded SSL/TLS library is a lightweight SSL/TLS library written in ANSI C and targeted for embedded, RTOS, and resource-constrained environments – primarily because of its small size, speed, and feature set. For Keil MDK and uVision users we provide a CMSIS pack that enables them […]
Read MoreMore TagBetter ASN.1 Support with Templates
wolfSSL has significant improvements on how we parse and encode ASN.1 data like certificates and keys. Parsing X.509 certificates, and RSA and ECC keys is important to do correctly. In fact, vulnerabilities come from not checking the validity of the encoding correctly! Reading outside the encoded data can result in crashing of your application or […]
