Package: libstrongswan (5.9.13-2 and others)

strongSwan utility and crypto library

The strongSwan VPN suite uses the native IPsec stack in the standard Linux kernel. It supports both the IKEv1 and IKEv2 protocols.

This package provides the underlying libraries of charon and other strongSwan components. It is built in a modular way and is extendable through various plugins.

Some default (as specified by the strongSwan projet) plugins are included. For libstrongswan (cryptographic backends, URI fetchers and database layers):

 - aes (AES-128/192/256 cipher software implementation)
 - constraints (X.509 certificate advanced constraint checking)
 - dnskey (Parse RFC 4034 public keys)
 - drbg (NIST SP-800-90A Deterministic Random Bit Generator)
 - fips-prf (PRF specified by FIPS, used by EAP-SIM/AKA algorithms)
 - gmp (RSA/DH crypto backend based on libgmp)
 - hmac (HMAC wrapper using various hashers)
 - md5 (MD5 hasher software implementation)
 - mgf1 (Mask Generation Functions based on the SHA-1, SHA-256 and SHA-512)
 - nonce (Default nonce generation plugin)
 - pem (PEM encoding/decoding routines)
 - pgp (PGP encoding/decoding routines)
 - pkcs1 (PKCS#1 encoding/decoding routines)
 - pkcs8 (PKCS#8 decoding routines)
 - pkcs12 (PKCS#12 decoding routines)
 - pubkey (Wrapper to handle raw public keys as trusted certificates)
 - random (RNG reading from /dev/[u]random)
 - rc2 (RC2 cipher software implementation)
 - revocation (X.509 CRL/OCSP revocation checking)
 - sha1 (SHA1 hasher software implementation)
 - sha2 (SHA256/SHA384/SHA512 hasher software implementation)
 - sshkey (SSH key decoding routines)
 - x509 (Advanced X.509 plugin for parsing/generating X.509 certificates/CRLs
   and OCSP messages)
 - xcbc (XCBC wrapper using various ciphers)
 - attr (Provides IKE attributes configured in strongswan.conf)
 - kernel-netlink [linux] (IPsec/Networking kernel interface using Linux
   Netlink)
 - kernel-pfkey [kfreebsd] (IPsec kernel interface using PF_KEY)
 - kernel-pfroute [kfreebsd] (Networking kernel interface using PF_ROUTE)
 - resolve (Writes name servers received via IKE to a resolv.conf file or
   installs them via resolvconf(8))
