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. |
