Base 64 Expressions

Question

The decodehexstring function in Base64 Expressions doesn't return the original text. 
 Demo example - 
 decodehexstring(md5hash("jit")) returns ";n�S��,���F�" instead of "jit".

 decodehexstring() and md5hash() are completely different functions for different purposes. So, these functions never do the opposite of the other. 
 md5hash() 
 
 This function will return the 128-bit digest of the input string in a hex format so that the 128 bit can be easily represented with just 32 characters. 
 
 decodehexstring() 
 
 This function accepts a hex string and returns the equivalent text. 
 
 Eg. if the hex string is 5E 4B 31 then it will be separated into pairs of 2 characters (HEX CODE) and the text equivalent for the corresponding hex code will be returned. For this example the output will be ^K1 
 
 5E - ^ 
 4B - K 
 31 - 1
