Change the 'man' directory to 'apps'. Yes I wish cvs
could rename too :-(

The default is 65537. + +=item B<-rand file(s)> + +a file or files containing random data used to seed the random number +generator. Multiple files can be specified separated by a OS-dependent +character. For MS-Windows, the separator is B<;>. For OpenVMS, it's +B<,>. For all others, it's B<:>. + +=item B<numbits> + +the size of the private key to generate in bits. This must be the last option +specified. The default is 512. + +=back + +=head1 NOTES + +RSA private key generation essentially involves the generation of two prime +numbers. When generating a private key various symbols will be output to +indicate the progress of the generation. A B<.> represents each number tested. +A B<+> means a number has passed a single primality test. A newline means that +the number has passed all the prime tests (currently set to 5 single tests). + +Because key generation is a random process the time taken to generate a key +may vary somewhat. + +=head1 BUGS + +A quirk of the prime generation algorithm is that it cannot generate small +primes. Therefore the number of bits should not be less that 64. For typical +private keys this will not matter because for security reasons they will +be much larger (typically 1024 bits). + +=head1 SEE ALSO + +gendsa(1) |
