NAME¶
rand - generate pseudo-random bytesSYNOPSIS¶
openssl rand [ -out file] [ -rand file(s)] [ -base64] [ -hex] numDESCRIPTION¶
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.
- -hex
- Show the output as a hex string.
