known-plaintext attack

Hi,

its me again.

I do have a encrypted file and also do have the plaintext. How can I find out the encryption algo and how can i get the key?
They both have the same length. Thats all i know

Ciphertext hex is:

29 6E 0D 7D F1 37 48 C4 FC 80 46 C2 50 54 40 BB 4F AE A0 08 D3 BD 38 7D AF 56 2C E9 27 3E 50 6A 30 45 AC AC 13 7C 4A DC A7 0F A5 56 4E 5C C0 13 2D 07 C8 78 1F 4F 52 E8

Plaintext hex is:

52 75 6E 53 63 72 69 70 74 31 3D 4D 6F 64 65 73 4D 61 6E 61 67 65 72 2E 4C 6F 61 64 53 65 6C 65 63 74 65 64 4D 61 74 65 72 69 61 6C 73 28 22 44 65 66 61 75 6C 74 22 29
