The file should be owned -by the super-user, -and its permissions should be set to block all access by others. -.LP -The file is a sequence of entries and include directives. -Here is an example. -.LP -.RS -.nf -# /etc/ipsec.secrets - strongSwan IPsec secrets file -192.168.0.1 %any : PSK "v+NkxY9LLZvwj4qCC2o/gGrWDF2d21jL" - -: RSA moonKey.pem - -alice@strongswan.org : EAP "x3.dEhgN" - -carol : XAUTH "4iChxLT3" - -dave : XAUTH "ryftzG4A" - -# get secrets from other files -include ipsec.*.secrets -.fi -.RE -.LP -Each entry in the file is a list of optional ID selectors, followed by a secret. -The two parts are separated by a colon (\fB:\fP) that is surrounded -by whitespace. If no ID selectors are specified the line must start with a -colon. -.LP -A selector is an IP address, a Fully Qualified Domain Name, user@FQDN, -\fB%any\fP or \fB%any6\fP (other kinds may come). -.LP -Matching IDs with selectors is fairly straightforward: they have to be -equal. In the case of a ``Road Warrior'' connection, if an equal -match is not found for the Peer's ID, and it is in the form of an IP -address, a selector of \fB%any\fP will match the peer's IP address if IPV4 -and \fB%any6\fP will match a the peer's IP address if IPV6. -Currently, the obsolete notation \fB0.0.0.0\fP may be used in place of -\fB%any\fP. -.LP -In IKEv1 an additional complexity -arises in the case of authentication by preshared secret: the -responder will need to look up the secret before the Peer's ID payload has -been decoded, so the ID used will be the IP address. -.LP -To authenticate a connection between two hosts, the entry that most -specifically matches the host and peer IDs is used. An entry with no -selectors will match any host and peer. More specifically, an entry with one -selector will match a host and peer if the selector matches the host's ID (the -peer isn't considered). Still more specifically, an entry with multiple -selectors will match a host and peer if the host ID and peer ID each match one -of the selectors. If the key is for an asymmetric authentication technique -(i.e. a public key system such as RSA), an entry with multiple selectors will -match a host and peer even if only the host ID matches a selector (it is -presumed that the selectors are all identities of the host). -It is acceptable for two entries to be the best match as -long as they agree about the secret or private key. -.LP -Authentication by preshared secret requires that both systems find the -identical secret (the secret is not actually transmitted by the IKE -protocol). If both the host and peer appear in the selector list, the -same entry will be suitable for both systems so verbatim copying -between systems can be used. This naturally extends to larger groups -sharing the same secret. Thus multiple-selector entries are best for PSK -authentication. -.LP -Authentication by public key systems such as RSA requires that each host -have its own private key. A host could reasonably use a different private keys -for different interfaces and for different peers. But it would not -be normal to share entries between systems. Thus thus no-selector and -one-selector forms of entry often make sense for public key authentication. -.LP -The key part of an entry must start with a token indicating the kind of -key. The following types of secrets are currently supported: -.TP -.B PSK -defines a pre-shared key -.TP -.B RSA -defines an RSA private key -.TP -.B ECDSA -defines an ECDSA private key -.TP -.B P12 -defines a PKCS#12 container -.TP -.B EAP -defines EAP credentials -.TP -.B NTLM -defines NTLM credentials -.TP -.B XAUTH -defines XAUTH credentials -.TP -.B PIN -defines a smartcard PIN -.LP -Details on each type of secret are given below. -.LP -Whitespace at the end of a line is ignored. At the start of a line or -after whitespace, \fB#\fP and the following text up to the end of the -line is treated as a comment. -.LP -An include directive causes the contents of the named file to be processed -before continuing with the current file. The filename is subject to -``globbing'' as in \fIsh\fP(1), so every file with a matching name -is processed. Includes may be nested to a modest -depth (10, currently). If the filename doesn't start with a \fB/\fP, the -directory containing the current file is prepended to the name. The -include directive is a line that starts with the word \fBinclude\fP, -followed by whitespace, followed by the filename (which must not contain -whitespace). -.SS TYPES OF SECRETS -.TP -.B [ <selectors> ] : PSK <secret> -A preshared \fIsecret\fP is most conveniently represented as a sequence of -characters, which is delimited by double-quote characters (\fB"\fP). -The sequence cannot contain newline or double-quote characters. -.br -Alternatively, preshared secrets can be represented as hexadecimal or Base64 -encoded binary values. A character sequence beginning with -.B 0x -is interpreted as sequence of hexadecimal digits. -Similarly, a character sequence beginning with -.B 0s -is interpreted as Base64 encoded binary data. -.TP -.B : RSA <private key file> [ <passphrase> | %prompt ] -.TQ -.B : ECDSA <private key file> [ <passphrase> | %prompt ] -For the private key file both absolute paths or paths relative to -\fI/etc/ipsec.d/private\fP are accepted. If the private key file is -encrypted, the \fIpassphrase\fP must be defined. Instead of a passphrase -.B %prompt -can be used which then causes the daemon to ask the user for the password -whenever it is required to decrypt the key. -.TP -.B : P12 <PKCS#12 file> [ <passphrase> | %prompt ] -For the PKCS#12 file both absolute paths or paths relative to -\fI/etc/ipsec.d/private\fP are accepted. If the container is -encrypted, the \fIpassphrase\fP must be defined. Instead of a passphrase -.B %prompt -can be used which then causes the daemon to ask the user for the password -whenever it is required to decrypt the container. Private keys, client and CA -certificates are extracted from the container. To use such a client certificate -in a connection set leftid to one of the subjects of the certificate. -.TP -.B <user id> : EAP <secret> -The format of \fIsecret\fP is the same as that of \fBPSK\fP secrets. -.br -\fBEAP\fP secrets are IKEv2 only. -.TP -.B <user id> : NTLM <secret> -The format of \fIsecret\fP is the same as that of \fBPSK\fP secrets, but the -secret is stored as NTLM hash, which is MD4(UTF-16LE(secret)), instead of as -cleartext. -.br -\fBNTLM\fP secrets can only be used with the \fBeap-mschapv2\fP plugin. -.TP -.B [ <servername> ] <username> : XAUTH <password> -The format of \fIpassword\fP is the same as that of \fBPSK\fP secrets. -\fBXAUTH\fP secrets are IKEv1 only. -.TP -.B : PIN %smartcard[<slot nr>[@<module>]]:<keyid> <pin code> | %prompt -The smartcard selector always requires a keyid to uniquely select the correct -key. The slot number defines the slot on the token, the module name refers to -the module name defined in strongswan.conf(5). -Instead of specifying the pin code statically, -.B %prompt -can be specified, which causes the daemon to ask the user for the pin code. -.LP - -.SH FILES -/etc/ipsec.secrets -.SH SEE ALSO -ipsec.conf(5), strongswan.conf(5), ipsec(8) -.br -.SH HISTORY -Originally written for the FreeS/WAN project by D.
