SYNOPSIS

pfstore [-n] [-d] -f pfsfile identity

OPTIONS

-n

Create the file

-d

Delete given identity from the store

-f pfsfile

Specifies file that holds identity/pass-phrase pairs

DESCRIPTION

pfstore is used to create and manage files that hold identity/pass-phrase pairs. It is primarily used to manage the owampd.pfs file for owampd.

If the -d option is not specified, then pfstore prompts the caller for a pass-phrase. The pass-phrase is hex-encoded and saved in the pfsfile with the associated identity. If the given identity already exists in the pfsfile, the previous pass-phrase is overwritten with the new one.

pfsfiles generated by pfstore are formatted for use with OWAMP.

PFSFILE FORMAT

pfstore generates lines of the format:

test   54b0c58c7ce9f2a8b551351102ee0938

An identity, followed by whitespace, followed by a variable-length hex-encoded pass-phrase.

No other text is allowed on these lines; however, comment lines may be added. Comment lines are any line where the first non-white space character is '#'.

EXAMPLES

pfstore -f /etc/owampd/owampd.pfs testuser

Adds a pass-phrase for the identity testuser. The user is prompted for a pass-phrase. If the file does not exist, an error message will be printed and no action will be taken.

pfstore -f /etc/owampd/owampd.pfs -n testuser

Creates the file before doing the same as above. If the file already exists, an error message will be printed and no action will be taken.

pfstore -f /etc/owampd/owampd.pfs -d testuser

Deletes the identity testuser from the pfsfile. If the file does not exist, an error message will be printed and no action will be taken.

SECURITY CONSIDERATIONS

The pass-phrases in the pfsfile are not encrypted in any way; they are simply hex-encoded. The security of these pass-phrases is completely dependent upon the security of the filesystem and the discretion of the system administrator.

RESTRICTIONS

identity names are restricted to 80 characters.
