Using Solaris 9 and 10. What we want to do is set up global rules for our password files to restrict all users, not only new ones set up with the rules but also the ones that have been sitting on the system for years. Is there a global way to force all users to change their password every 90...

genrsa

GENRSA(1SSL)							      OpenSSL							      GENRSA(1SSL)

NAME

       genrsa - generate an RSA private key

SYNOPSIS

       openssl genrsa [-out filename] [-passout arg] [-des] [-des3] [-idea] [-f4] [-3] [-rand file(s)] [-engine id] [numbits]

DESCRIPTION

       The genrsa command generates an RSA private key.

OPTIONS

       -out filename
	   the output filename. If this argument is not specified then standard output is used.

       -passout arg
	   the output file password source. For more information about the format of arg see the PASS PHRASE ARGUMENTS section in openssl(1).

       -des|-des3|-idea
	   These options encrypt the private key with the DES, triple DES, or the IDEA ciphers respectively before outputting it. If none of these
	   options is specified no encryption is used. If encryption is used a pass phrase is prompted for if it is not supplied via the -passout
	   argument.

       -F4|-3
	   the public exponent to use, either 65537 or 3. The default is 65537.

       -rand file(s)
	   a file or files containing random data used to seed the random number generator, or an EGD socket (see RAND_egd(3)).  Multiple files
	   can be specified separated by a OS-dependent character.  The separator is ; for MS-Windows, , for OpenVMS, and : for all others.

       -engine id
	   specifying an engine (by its unique id string) will cause genrsa to attempt to obtain a functional reference to the specified engine,
	   thus initialising it if needed. The engine will then be set as the default for all available algorithms.

       numbits
	   the size of the private key to generate in bits. This must be the last option specified. The default is 512.

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 . represents each number which has passed an initial sieve test, + means a number has
       passed a single round of the Miller-Rabin primality test. A newline means that the number has passed all the prime tests (the actual number
       depends on the key size).

       Because key generation is a random process the time taken to generate a key may vary somewhat.

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).
