Call to undefined function sodium_crypto_secretbox_keygen()

Hello to all!

Call to undefined function sodium_crypto_secretbox_keygen()

I didn't find this function when search this text on Sodium package. But another functions from _secretbox exists in Sodium package:

• sodium_crypto_secretbox
• sodium_crypto_secretbox_open

How to generate secret key for sodium_crypto_secretbox if sodium_crypto_secretbox_keygen() function does not exist?
 

P.S. I found that this code could be the solution, but is this solution safe enough?
$secret_key = random_bytes(SODIUM_CRYPTO_SECRETBOX_KEYBYTES);

Yes, random_bytes() is exactly what you want.

Forgive the oversight. I'll get these in 1.4.0, due to be released on or before November 30 (PHP 7.2 release date).

Thanks a lot!

The unit tests are still running, but it should be fixed in 8843e0d which will be included in v1.4.0 once it's released. If any tests fail, I'll fix it tonight.
