Your friend, Liara, has encrypted all her life secrets, using the one of the best encryptions available in the world, the AES. She has challenged you that no matter what, you can never read her life secrets.

The encryption service is running at :- 128.199.224.175:33000 The binary file is named aes_enc.

Her encrypted life secrets are as follows :-

0000 - 40 87 68 1a b0 23 73 c4 61 44 b4 c0 21 f1 63 0b @.h..#s.aD..!.c.

0010 - 73 e9 0d 38 e4 bd d8 33 41 64 2c 43 85 d4 54 0e s..8...3Ad,C..T.

0020 - f5 bc 8c 02 db ee 0d e8 d6 29 81 3a 5f cb 63 bd .........).:_.c.

Note: Since some teams were having issues with the buffering of the I/O streams when executing the binary remotely, we have updated the binary file, to flush the output streams properly. The modified binary is named aes_enc_unbf, and will be running on 128.199.224.175:33100
