NAME
rand - generate pseudo-random bytes SYNOPSIS
openssl rand [-out file] [-rand file(s)] [-base64] num DESCRIPTION
The rand command outputs num pseudo-random bytes after seeding the random number generator once. As in other openssl command line tools, PRNG seeding uses the file $HOME/.rnd or .rnd in addition to the files given in the -rand option. A new $HOME/.rnd or .rnd file will be written back if enough seeding was obtained from these sources. OPTIONS
-out file Write to file instead of standard output. -rand file(s) Use specified file or files or EGD socket (see RAND_egd(3)) for seeding the random number generator. Multiple files can be specified separated by a OS-dependent character. The separator is ; for MS-Windows, , for OpenVMS, and : for all others. -base64 Perform base64 encoding on the output. SEE ALSO

NAME
gendsa - generate a DSA private key from a set of parameters SYNOPSIS
openssl gendsa [-out filename] [-des] [-des3] [-idea] [-rand file(s)] [-engine id] [paramfile] DESCRIPTION
The gendsa command generates a DSA private key from a DSA parameter file (which will be typically generated by the openssl dsaparam com- mand). OPTIONS
-des|-des3|-idea These options encrypt the private key with the DES, triple DES, or the IDEA ciphers respectively before outputting it. A pass phrase is prompted for. If none of these options is specified no encryption is used. -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 it's unique id string) will cause req 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. paramfile This option specifies the DSA parameter file to use. The parameters in this file determine the size of the private key. DSA parameters can be generated and examined using the openssl dsaparam command. NOTES
DSA key generation is little more than random number generation so it is much quicker that RSA key generation for example. SEE ALSO
