Decipher POCSAG

Dear community!
First of all i have to apologise for my bad English-skills - I try to do my best but I´m Austrian ;)
For a few weeks I try to gain insight into the world of SDR. Now i located a POCSAG signal BUT the messages are encrypted (you can see it on the pic). I use SDRSharp and PDW Pager for getting a signal and decoding it - is there any software which makes it possible to decipher the enctrypted message?
Thank you for your answers!

Huh this is interesting. I don't enough about this to really help you out but in general in terms of encryption this stuff looks hashed. Meaning that it's going to be very difficult to decipher without having any idea what they key could be or the hashing method used.

Greetings,
have you setup PDW to automatically decode POCSAG packets?

Go to Options -> Options and Click Enable Pocsag Decoding, and ensure the 512, 1200 and 2400 boxes are all checked. Also, ensure Enable Flex Decoding is enabled and that the 1600, 3200 and 6400 boxes are all checked.

Should work then.

Hm... It´s possible for me to get the decoded messenges - but I don´t know what to do next?
