Generator for Plain RSA keys
Syntax:
plainrsa-gen [-b bits] [-e pubexp] [-f outfile]
Runs on:
QNX OS
Description:
The plainrsa-gen command 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
The bit length of the key. The default is 1024, and the recommended length
is 2048, or even 4096 bits. Note that generating longer keys takes a
longer time.
-e pubexp
The value of the RSA public exponent. The default is 0x3. Don't
change this unless you really know what you are doing!
-f outfile
The 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...
