Hi all

I'm not sure is this the right place to post this, other places are strongly oriented to the real programming. However...

I know some MD5 hashes contains only numbers or letters, but I don't know which one. Some string X gives only letters in the hash, Y gives only numbers.

Do you know which strings give those hashes?

No.

"Trying to Encrypt Your DB with MD5? ******* already does it. Try now!"

WTF.

Edit: But you can surely find one.

Since you're talking about a hash that outputs 32 characters (in hexadecimal, which presumably is what you're talking about), each character has a 5/8 chance of being a decimal digit and a 3/8 chance of being a letter.

That means there's a (5/8)^32 chance of them all being decimal digits.

Which means it will take on average 1/(5/8)^32 guesses to get such a hash, which is easily small enough for a computer to brute force.

Finding a hash with just letters is about 8 million times harder than that.

Good explanation that hex contains both decimal digits and letters (A-F).

Well, 3,5 million guesses isn't so much.

How should I brute force that?

This byte sequence (in hex) resulted in an MD5 hash of `68 96 55 13 90 19 02 12 35 06 45 31 90 73 51 46`
