asa01(config)# crypto key generate rsa label sslvpnkey                             
ERROR: % Invalid input detected at '^' marker. 

It seems I'm missing options for crypto:

asa01(config)# crypto ?

configure mode commands/options:
  engine  Configure crypto engine
  isakmp  Configure ISAKMP

UPDATE: I was in multi-context mode, after switching to single context, webvpn command is now recognized (with only the remove option) and crypto now only has the ca option.

Why am I missing options?

Cisco Adaptive Security Appliance Software Version 9.1(7) <system>

As I asked on your previous NE question, you're running in multiple context mode. The "<system>" at the end of the version line is the dead giveaway. You cannot set RSA keys from the system context. You need to be in a specific context -- or turn multiple context mode off.

  • please see update comment at bottom of post, i'll update the sh ver output when I get a chance, <system> indicator is gone, in single context mode. – Don P Oct 22 '18 at 18:37
