There’s no such thing as a a “reverse hash calculator” though. Hash is meant to be one-way encryption.
I’ve checked it, yes that’s the MD5 of that string.
It’s not really encryption, it’s validation. An encrypted message has the same amount of information as the orginal message, thirty-two bytes can never contain all the information in a much longer message. For instance if the original message was the first one million digits of PI, the hash code would still only be 32 bytes. There are infinitely many messages that would have the same hash code, but the probability that two distinct messages would have the same hash code purely by chance is about one in two raised to (the number of bytes times eight). For a thiry two byte hash code that would be about one in 1e77.
BTW, it appears to me that 9e c4 c1 29 49 a4 f3 14 74 f2 99 05 8c e2 b2 2a only contains 16 bytes. What am I missing?
