rand ? generate pseudo-random bytes |
openssl rand [?out file] [?rand file(s)] [?base64] num |
The rand command outputs num pseudo-random bytes after seeding the random number generater 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. |
?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 OpenVSM, and : for all others. |
?base64 |
Perform base64 encoding on the output. |
