NAME

       plainrsa-gen — generator for Plain RSA keys

SYNOPSIS

       plainrsa-gen [-b bits] [-e pubexp] [-f outfile] [-h]

DESCRIPTION

       plainrsa-gen can be used to generate Plain RSA keys for authentication purposes.  Using Plain RSA keys is
       optional.  Other possibilities are Pre-shared keys or X.509 certificates.

       -b bits
               bit length of the key.  Default is 1024, recommended length is 2048 or even 4096 bits.  Note that
               generating longer keys takes longer time.

       -e pubexp
               value of RSA public exponent.  Default is 0x3.  Don't change this unless you really know what you
               are doing!

       -f outfile
               outfile  instead  of  stdout.   If the file already exists it won't be overwritten.  You wouldn't
               like to lose your private key by accident, would you?

OUTPUT FILE FORMAT

       This is the secret private key that should never leave your computer:

       : RSA   {
               # RSA 1024 bits
               # pubkey=0sAQOrWlcwbAIdNSMhDt...
               Modulus: 0xab5a57306c021d3523...
               PublicExponent: 0x03
               PrivateExponent: 0x723c3a2048...
               Prime1: 0xd309b30e6adf9d85c01...
               Prime2: 0xcfdc2a8aa5b2b3c90e3...
               Exponent1: 0x8cb122099c9513ae...
               Exponent2: 0x8a92c7071921cd30...
               Coefficient: 0x722751305eafe9...
         }

       The line pubkey=0sAQOrW... of the private key contains a public key that should be stored  in  the  other
       peer's configuration in this format:

       : PUB 0sAQOrWlcwbAIdNSMhDt...

       You can also specify from and to addresses for which the key is valid:

       0.0.0.0/0 10.20.30.0/24 : PUB 0sAQOrWlcwbAIdNSMhDt...
