PLAINRSA-GEN(8)                          BSD System Manager's Manual                         PLAINRSA-GEN(8)

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 more time.

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

     -f outfile
             write the resulting key to 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...
