Question

Answer 1

+3 A:

Probably encryption followed by Base64. Many apps encrypt their connection strings.

Encryption is a safe bet, encryption algorithms do not necessarily map completely to a printable charset, thus the need to Base64 encode it (which is evident from the == suffix). Another alternative is to use a different base type algorithm, like Base32

Answer 2

A:

Write a program that converts both to binary. Scan for similarities that way.

It will be impossible to see patterns that are not exactly 8 bits in ascii.

One similarity is that `rijcmlq` begins every encoded string. It seems to be a signature of some sort

Rijndael (also known as AES) is a pretty well-known, widely implemented symmetric cypher. It does not produce a signature by itself though; it could be so that a Rijndael-encrypted block is prepended with a header of some kind.
