strongswan: An IPsec implementation for Linux1

Package available in: [trunk] [8.0] [7.0] [6.0]

strongSwan is an OpenSource IPsec implementation for the Linux operating system. It is based on the discontinued FreeS/WAN project and the X.509 patch which we developped over the last three years. In order to have a stable IPsec platform to base our future extensions of the X.509 capability on, we decided to lauch the strongSwan project.

The focus is on - simplicity of configuration - strong encryption and authentication methods - powerful IPsec policies supporting large and complex VPN networks

strongSwan features includes: - both on Linux 2.4 (KLIPS) and Linux 2.6 (native IPsec) kernels. - Fast connection startup and periodic update using ipsec starter - Automatic insertion and deletion of IPsec policy based firewall rules - strong 3DES, AES, Serpent, Twofish, or Blowfish encryption - NAT-Traversal (RFC 3947) and support of virtual IPs and IKE Mode Config - Dead Peer Detection (DPD, RFC 3706) takes care of dangling tunnels - Authentication based on X.509 certificates or preshared keys - Authentication based on X.509 certificates or preshared keys - Generation of a default self-signed certificate during first strongSwan startup - Retrieval and local caching of Certificate Revocation Lists via HTTP or LDAP - Full support of the Online Certificate Status Protocol (OCSP, RCF 2560) - CA management (OCSP and CRL URIs, default LDAP server) - Powerful IPsec policies based on wildcards or intermediate CAs - Group policies based on X.509 attribute certificates ( RFC 3281) - Optional storage of RSA private keys and certificates on a smartcard - Smartcard access via standardized PKCS #11 interface - PKCS #11 proxy function offering RSA decryption services via whack
