Split key

[Mohan Radhakrishnan]

Hi,
       I came across a reference to paperkey in this forum which seems
to be splitting a public key into two parts. 
 
Does this procedure look like a sensible thing to do ?
 
1. Generate key pair in keyring.
2. Encrypt symmetric key using this public key.
3. Remove public key from keyring. Is this possible
4. Separate a part of the public key and give it to a custodian.
 
 
1. Reconstruct it and import into the keyring.
2. Decrypt symmetric key using this public key.
3. Use decrypted symmetric key to encrypt whatever I want.
 
I am just looking at a way to ensure that a key can be resconstructed
from custody. The GPG keyring password can also be encrypted using the
same public key. Just that there is a way to split and ensure that
everything is not in one place so that security is enhanced.
 
Thanks,
Mohan
