Option for regenerating key pairs does not work correctly

[MichaelHallik]

• Start the CryptoLibrary CLI tool.
• Chose [Open Config -> Configure key pair -> Generate key pair].
• This will present us with a question: "Do you want to regenerate the key pair? (Use arrow keys.)"
• You have two options: 'Yes' and 'No'.

However,

‘No’ currently does not have an effect at all: it simply does nothing.

Moreover, choosing ‘Yes’ will not result in the regeneration of an existing key pair, but will simply (always) create a new key pair (regardless of whether a key pair does or does not already exist)
