Endpoint Encryption

Hello everyone.

I have pgp netsahre versión 10 and i have defined several private keys, with their passphrases to encrypt some items, i'm encrypting items with only one private key at once, and sometimes i only want to work with items protected with only one private key and i want to lock the access to others private key's protected item but i don't want to clear all the passphrases from memory, i just want to clear the passphrases that don't want to use. How can i clear the cache for specific passphases without clearing all the cache?

Thanks in advance.

I believe the only option is to clear the cache, there is no option to clear specific things from the cache, its all or nothing.

Thanks Alex_CST for answer so soon.

Ii have not found any way to do it, but i still believe that if PGP can let you to insert passphrases for private keys individually then it can let you to disable the private keys passphrase individually too.
