Please add “30 second” and “1 minute” as options.
I’m using AxCrypt (premium) for crypting private SSH keys.
Putty (SSH client) need key only when make a connection to SSH.
After that key can be encrypted again, no need for decrypted version of file.
Or better, make option (on right click) “Encrypt for” and submenu with intervals (30 seconds, 1 minute, etc…)
