Generator for Plain RSA keys


plainrsa_gen [-b bits] [-e pubexp] [-f outfile] [-h]

Runs on:

QNX Neutrino


-b bits
The bit length of the key. The default is 1024; the recommended length is 2048 or even 4096 bits. Note that generating longer keys takes more time.
-e pubexp
The value of the RSA public exponent. The default is 0x3.
Note: Don't change this unless you really know what you are doing!
-f outfile
Write the resulting key to outfile instead of to stdout. If the file already exists, it isn't overwritten, so that you won't accidentally lose your private key.
Display help.
-i filename
(QNX Neutrino 7.0 or later) Specify the input source for format conversion.


You can use plainrsa_gen to generate Plain RSA keys for authentication purposes. Using Plain RSA keys is optional. Other possibilities are pre-shared keys or X.509 certificates.

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: : PUB 0sAQOrWlcwbAIdNSMhDt...
