The problem is that the external program output from pgp operations usually contain multiple lines like below 

pgp:encrypt (3157:current local time aa-bb-cc)
/xxxx:open keyrings (1006:public keyring)
/xxxx:open keyrings (1007:private keyring)
yyyyy:encrypt (1030:key added to recipient list)
yyyyy:encrypt (1050:key added as signer)
sample.txt:encrypt (3090:operation failed, file not found)

Here, the last line is what matters to me and this is what needs to be compared to the error strings I mentioned in my original post. I am still unable to successfully catch the appropriate errors.
