Is it possible to decrypt this message with partially known data? The following highlighted text must contains 547a5e0e008be33730158d63ce844e67 data. I don't know about encryption method and key.

Is it possible to decrypt it?



Or just give me some idea about encryption method that they use to encrypt it.
The first 32 bytes seem to be the ASCII representation of a 16-byte hexadecimal string. Possibly an Initialization Vector (IV) or similar. That would leave us with 88 bytes remaining. My guess is that this encryption is made by some 128-bit block cipher (e.g., AES-128), using some mode of operation such as CTR or CBC. Note that 88 bytes is not a valid ciphertext size when using AES-128 and CBC mode, but maybe there are 8 bytes that are not part of the ciphertext.

It would be nice if you provide a textual version of the highlighted hexadecimal data.
