wolfCLU version 0.1.4 is now available! In this release of the wolfSSL command line utility (CLU) there were additions to the x509 command, more subject alternative name attributes supported, and a couple of minor fixes / maintenance items. The command line utility is a great time saver for quickly creating keys, certificates, signatures, and hashes […]
Read MoreMore TagwolfSSL is extending wc_PKCS7_VerifySignedData streaming
wolfSSL, a TLS library for embedded devices, not only handles the TLS protocol, but also supports bundle file handling functions specified by PKCS#7 (bundle file encoding, decoding, content extraction, signature verification). wolfSSL continues to extend this PKCS#7 handling functionality. wolfSSL is currently extending our wc_PKCS7_VerifySignedData() API to handle PKCS#7 bundle data with multipart and indefinite […]
Read MoreMore TagwolfSSL Updated Support for Kerberos 5 1.21.1
wolfSSL release 5.6.4 includes support for Kerberos 5 1.21.1. Kerberos is a network authentication protocol using modern cryptography to secure communications. The cryptography in the protocol is strong enough so that a client can prove its identity to a server (and vice versa) across an insecure network connection. You can improve the security of Kerberos […]
