Formatting The Output Files & Matching Keys

I have the following 2 output files, one contain the standard output after i decrypt the encrypted file and another keys listed from the gpg trust db,

Provider File:

Code:

gpg: encrypted with 2048-bit RSA key, ID 96301328, created 2014-04-29
      "JKL <400@abc.com>"
gpg: encrypted with 2048-bit ELG-E key, ID ECB614CF, created 2002-02-06
      "GHI <300@abc.com>"
gpg: encrypted with 2048-bit ELG-E key, ID 1EB07C50, created 2014-02-20
      "ABC <100@abc.com>"
gpg: WARNING: message was not integrity protected

GPG Public Keys:

Code:

pub   1024D/17CD2890 2014-02-20
uid                  ABC <100@abc.com>
sub   2048g/1EB07C50 2014-02-20

pub   2048D/8911CBCA 2014-04-03
uid                  DEF <200@abc.com>
sub   2048g/F0E4D9C3 2014-04-03

pub   1024D/CB26F4C3 2002-02-06
uid                  GHI <300@abc.com>
sub   2048g/ECB614CF 2002-02-06

pub   2048R/547A8D75 2014-04-29
uid                  JKL <400@abc.com>
sub   2048R/96301328 2014-04-29

My requirements
1) After i decrypt the file i need to make sure there are three keys embedded or used to encrypt the file, i have to get the count from the file decryption output as shown in "Provider File" excerpt above.
2) I have to search for appropriate UID's and take the corresponding values 96301328,ECB614CF,1EB07C50 from "Provider File" and match those values with "GPG Public Keys" file and email out which key is different and associated email id.

For 1, i have following snippet awk -F"[<>]" '/@/ {L++ ; print $2} END{print L+0}' from a friend but how do i supress the email id's and just print only count?
For 2, I am still working on it?

Appreciate your inputs please help.

crypt

crypt(1)						      General Commands Manual							  crypt(1)

NAME

       crypt - encode/decode

SYNOPSIS

       crypt key < input.File > output.File

DESCRIPTION

       The  command reads from the standard input and writes on the standard output.  You must supply a key which selects a particular transforma-
       tion.  If no password is given, demands a key from the terminal and turns off printing while the  key  is  being  typed	in.   The  command
       encrypts and decrypts with the same key.

       Files encrypted by are compatible with those treated by the ed, ex and vi editors in encryption mode.

       The security of encrypted files depends on three factors: the fundamental method must be hard to solve, direct search of the key space must
       be infeasible, and sneak paths by which keys or clear text can become visible must be minimized.

       The command implements a one-rotor machine designed along the lines of the German Enigma, but with a 256-element rotor.	Methods of  attack
       on such machines are known, but not widely; moreover the amount of work required is likely to be large.

       The transformation of a key into the internal settings of the machine is deliberately designed to be expensive, for example, to take a sub-
       stantial fraction of a second to compute.  However, if keys are restricted to three lowercase letters, then encrypted files can be read	by
       expending only a substantial fraction of five minutes of machine time.

       Since the key you choose is an argument to the command, it is potentially visible to users executing the command or a derivative.  To mini-
       mize this possibility, destroys any record of the key immediately upon entry.  The most vulnerable aspect of is the choice of keys and  key
       security.

EXAMPLES

       The following examples use KEY as the key to encrypt and decrypt files.	The first example encrypts the file naming the resulting encrypted
       file The second example decrypts the file naming the resulting decrypted file The third example prints the encrypted file in clear text.  $
       crypt KEY < plain.File > crypt.File $ crypt KEY < crypt.File > decrypt.File $ crypt KEY < crypt.File | pr
