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...
