Description-en: 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)
- 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)
- 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)
For libhydra (IKE daemon plugins):
- 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))
