What is at the end of PGP blob?

Question

I am trying to decrypt a portion of an email that is encrypted with PGP. In the examples I looked at, the end of the encrypted data had an "===" then some characters. Are they part of the format?

Example vNg===eWY7

This question appears to be off-topic as it's not a programming question. — nos, Jul 01 '14 at 13:29

It seems there is a newline character missing in-between the second and third equal sign. The message should be ending somewhat like this:

vNg==
=eWY7

The first two (it might be zero to two, depending on the encrypted input) equal signs are used as padding for the ASCII-armoring, as stated in section 6.3 of RFC 4880.

The third (last) equal sign introduces the checksum, es described in section 6.

Thanks. You are right, I lost the newline in my copy/paste. Thanks for the info. – cybergoof Jul 01 '14 at 17:37
