GNU Transport Layer Security Library 1.7.3

GNU Transport Layer Security Library is a library which implements a secure layer over a reliable transport layer such as TCP/IP. GNU Transport Layer Security Library implements the TLS 1.0 and SSL 3.0 protocols, accompanied with authentication methods such as X.509, OpenPGP, and SRP.
Main features:
- Support for TLS 1.1 and SSL 3.0 protocols
- Support for TLS extensions
- Support for authentication using the SRP protocol
- Support for authentication using both X.509 certificates
- and OpenPGP keys Support for X.509 and OpenPGP certificate handling.
- Supports all the strong encryption algorithms
- Supports compression
- Runs on most Unix platforms
Enhancements:
- Support for Proxy Certificates as per RFC 3820 were added.
- The --generate-proxy option was added to certtool.
- certtool --certificate-info now prints information for Proxy Certificates.
- New APIs were added to set proxy subject names and get or set a proxy cert extension.
- Parsing of pathLenConstraints in BasicConstraints with missing CA was fixed.
- A self-test was added to test for regressions of pathLenConstraint.
- Certtool now prints times in UTC when printing certificate/CRL info.
- Importing of ASCII armored OpenPGP keys was fixed.
