It almost appears to be or very close to a simple Base64 scheme with
maybe a shift or substitution somewhere.
For example, your patterns :
a aQ==
b cg==
c ew==
Now heres the results of a true Base64 encrypt :
a YQ==
b Yg==
c Yw==
As you see the results are very close. Hope this helps some.

Hi All,
I am trying to figure out the password encryption scheme used by some
software and haven't had much luck yet. I was wondering if anyone on
here might be able to give me some pointers.
A little while ago I remember some discussion on this list (I think it
was this list anyway) about decrypting passwords that were XOR
encrypted. I can't seem to find that discussion though.
I have a few example passwords and I can see a pattern emerging:
password crypted
a aQ==
b cg==
c ew==
aa aWo=
ab aXE=
cc e3g=
aaa aWpq
aab aWpx
abb aXFx
bbb cnFx
Thanks,
David
