Does anyone recognise this type of encryption? These are phone numbers consisting of 10 digits and starting with 0 but the encrypted text width is not 10 and does not start with the same character.

Perhaps it's encrypted with a AES outputting a single block using ANSI (or similar) encoding. – CodesInChaos Mar 19 at 11:47

Try changing the character encoding to something more natural. Then try some of these.

It's possible no encryption was used at all and that the strings were somehow encoded (base64 or similar), and that you don't use the correct character encoding in your display. The fact that it's obfuscated doesn't mean it's encrypted. – rath Mar 19 at 11:05
