I am using org.apache.commons.codec.digest.DigestUtils.md5Hex() from Apache-Commons-Codec to calculate the mD5 of a concatenated string , however I get different mD5 hashcode values for the same string.
I see the following output , my expectation is that it will be same for a given string , but looks like its not .Whats the issue here ?
I generate the MD5 Hashcode using the following code and I am on centos platform.
if (StringUtils.isNotBlank(concatenatedString)) {
concatenatedString = StringUtils.deleteWhitespace(concatenatedString);
//System.out.println("The concatenated string is "+concatenatedString);
md5Hash = DigestUtils.md5Hex(concatenatedString);
//System.out.println("The mD5 hashcode is "+md5Hash);
}
OutPut:

Your inputs aren't the same. The antepenultimate* (or hundreds) digit of the number after spin_prod_ is 2 4 1 3 respectively. (* One of my favorite little-used words.)
