PGP Encryption

Hi All,

I need to do PGP encryption using the Public Key of a Vendor.We are using PGP Command Line 9.9 build 110 in our UNIX machine.Let us know the sequence of steps which we should follow.We are trying to do the following activity:

1) IMPORT the public key 

2) SIGN the public key

3)TRUST the public key

4)Encrypt the file using the public key

pgp --import "Bob Smith.asc"

pgp --sign-key <user> --signer <signer> --sig-type <type> --passphrase <pass> [options]

pgp --set-trust key --trust complete

pgp -e report.doc -r "Bob Smith" --output newreport.pgp-v

However,

I am not able to import the public key.It's showing the following error:

4007:key failed signature check

~Thanks and Regards,

Arun
