Is it a MD5 hash?
#1
I have a set of input and output data.

Input: 1900
Output: 10339a1efa428511e44bccb4031ee11e

Input: 0
Output: 0151d34b712c525b812a3cd7ac58c9ec

Input: 1500
Output: 10b09226e0bd5b6e823be378b1ef6f33

The output is always 32 char long.


I guess the input value was hashed with MD5 with following piece of javascript code:
"encode","\u003dFLK324956yhl%$\u003d\u003dkey\u003dFnwer295*(\u0026*(\u0026%214\u003dgsidk\u003dIAFhioqwr21402814;f\u003dvm349","md5","javascript:checksum(\u0027","\u0027,\u0027","\u0027)",""]


Can anyone tell what actually it is doing, thanks a lot!

1. you should be very careful to post hashes here, because it is not allowed according to the forum rules, see for instance https://hashcat.net/forum/announcement-2.html
2. since you provided the plain text and some "code", I think we could make an exception and don't ban you, but next time please ask first about the problem and provide the information/code. Only after approvement of the Admin or Moderators, you should post hashes.

3. this seems to be very easy to solve, it is just:
salt = "=FLK324956yhl%$==key=Fnwer295*(&*(&%214=gsidk=IAFhioqwr21402814;f=vm349" (without codes)
algorithm = -m 10 = md5 ($pass . $salt)

for instance if pass = "1900" (without quotes):
echo -n '1900=FLK324956yhl%$==key=Fnwer295*(&*(&%214=gsidk=IAFhioqwr21402814;f=vm349' | md5sum
10339a1efa428511e44bccb4031ee11e

If pass = "0" (w/o quotes):
echo -n '0=FLK324956yhl%$==key=Fnwer295*(&*(&%214=gsidk=IAFhioqwr21402814;f=vm349' | md5sum
0151d34b712c525b812a3cd7ac58c9ec

etc

BTW: the salt is way too long for hashcat/oclHashcat, it is horrible long and not supported, but the algorithm is like -m 10 = md5 ($pass . $salt)
