 | Hi.
Can anyone recognize the type of encryption / cipher that was used to
turn the numbers on the left to the string on the right? I have many
more if it would help. There seems to be a direct correlation between
the two, but I can't really figure it out. I'm sure that someone with
more experience can easily recognize it. Anyone?
Thanks.

First, split it up into groups of three. It looks like some form of Base64
encoding, with an extra character tacked onto the front of each tuple:
10200 MTAy MDBf Mjkx ODk1 NzFf MjEz NTI1
10215 MTAy MTVf MzI3 ODU1 NTFf MjEz NTI1
10413 MTA0 MTNf MTY1 NjU5 MzFf MjEz NTI1
10835 MTA4 MzVf MzI3 OTA5 NTFf MjEz NTI1
108555 MTA4 NTU1 XzM0 MjQ5 Mjc3 NF8y MTM1 MjU=
108575 MTA4 NTc1 XzM0 MjY2 MDM1 NF8y MTM1 MjU=
10896 MTA4 OTZf MjY4 MTk5 OTFf MjEz NTI1
etc etc
The first tuple is only affected by the first three digits of the number,
and it appears to be a direct additive thing:
string[0] = string[0] + 16*digits[0]
string[1] = string[1] + 4*digits[1]
string[2] = string[2] + digits[2]
The rest should follow similarly, though I'm still working on it :)

| Can you explain this to me in more simpler terms? I'm not really
familiar with all this. Looks like MTAy = 102 and MTA4 = 108, etc. But
I found other 108 in the full list which did not have a corresponding
MTA4 (although they were not in the beginning).
Thanks

Ahhh ha hah hah ... heh. Damn. There was a bug in my Base64 decoder which
made it spew garbage. Anyhow, the strings you give are just standard Base64
encoded ASCII strings:

I'm afraid you'll have to figure out how to get the middle bit by yourself.
It's not a linear congruential generator-style construction, so who knows
