Which 2 way encryption method is this?
mbrubeck: Whatever it is, the encrypted version is Base64-encoded.  Here's a hexdump without the Base64 encoding.    00000000  29 67 02 94 c3 c7 1a c1  d6 cb aa 3c 55 5d 7f d8  |)g.........<U]..|

The decoded ciphertext is 32 bytes (256 bits), while the plaintext is 16 bytes (128 bits).  I think this suggests a 256-bit block cipher.  (Or maybe 128-bit block, especially if the input included a trailing newline or something?)  That doesn't narrow it down all that much, and if you don't have the key I'm not sure it's possible to narrow it down any further.
