Generating random data with OpenSSL One way to produce lots of seemingly random, hard to compress data is to leverage AES encryption through OpenSSL. This can be faster than just reading data from /dev/urandom as modern CPUs typically have dedicated AES instruction sets which openssl can leverage.
For OpenSSL 1.1 onwards, using current epoch as the seed:
openssl enc -aes-256-ctr -pbkdf2…
