I'm trying to decode a string like 'BHQsZMaQQok='.
All I know about the string is that it must be a number. I can find more encrypted string if it is necessary.

do you know what type of encryption was used to encrypt it in the first place? – PCG Dec 30 '13 at 12:08

1It looks like Base64 to me – drew Dec 30 '13 at 12:11

Decodes to hex 0474 2c64 c690 4289 – drew Dec 30 '13 at 12:17

It is a number of type long. I don't know anything about encryption algorithm. This is what I'm trying to do – Mentor Dec 30 '13 at 12:18

It's a base64 string, 8 bytes: 04 74 2C 64 C6 90 42 89
Interpreted as an IEEE754 double, it is 3.3121005957308838680392659232E-287
As a big-endian long: 320930284789842569
As a little-endian long: -8556117160291961852
One can only guess how to interpret it...

The number for this string is: 910619. I think this is a triple DES encription but can't find the secret key. – Mentor Dec 30 '13 at 13:47

@MShevroja Finding a triple DES key is not possible without more information about the key. Brute forcing the key (at minimum testing 2^112 values, possibly 2^168 values) is not feasible. – Maarten Bodewes Jan 01 '14 at 13:26
