LuaSec 0.5

LuaSec depends on OpenSSL, and integrates with LuaSocket to make it easy to add secure connections to any Lua applications or scripts.

This version includes:

• A new certificate (X509) API, which supports:

  • Reading the subject (identity) and issuer of the certificate.
  • Reading various X509 extensions, including email and dnsName.
  • Converting certificates to and from the standard ASCII PEM format.
  • Generating the fingerprint/digest of a certificate (using SHA1, SHA256 or SHA512).
  • Reading the certificate's expiration, serial number, and other info.

• The ability to get more detailed information from OpenSSL about why a certificate failed verification, for each certificate in the chain.

• Flags to force acceptance of invalid certificates, e.g. to allow the use of self-signed certificates in a Trust On First Use model.

• Flags to control checking CRLs for certificate revocation status.

• Support for ECDH cipher suites.

• An API to get the TLS 'finished' messages used for SASL channel binding (e.g. the SCRAM PLUS mechanisms).

The work in this release was undertaken by Kim Alvefur, Paul Aurich, Tobias Markmann, Bruno Silvestre and Matthew Wild.
