MD5 Algorithim Help?

Can anyone explain the stages to create an MD5 checksum (really simply), or direct me to a website that does.

I have tried the RFC 1321 algorithim from MIT Comp Science Lab, but step 3 makes no sense to me. Oh I'll be using VB but would rather have in English

    In cryptography, MD5 (Message-Digest algorithm 5) is a widely-used cryptographic hash function with a 128-bit hash value. As an Internet standard (RFC 1321), MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files.

    MD5 was designed by Ronald Rivest in 1991 to replace an earlier hash function, MD4. In 1996, a flaw was found with the design of MD5; while it was not a clearly fatal weakness, cryptographers began to recommend using other algorithms, such as SHA-1 (recent claims suggest that SHA-1 has been broken, however). In 2004, more serious flaws were discovered making further use of the algorithm for security purposes questionable.

    i'm an atheist, yet: a million) Correlation != causation (whilst that's possible to advise a causative dating between the two variables, demonstrating it is yet another count completely. As yet another possible hypothesis, how with reference to the Savanna-IQ interplay hypothesis?) 2) pattern length effects ought to in finished or partly clarify the stated modifications, reckoning on the learn we are speaking approximately. there is another low-putting methodological fruit i will forget approximately as nicely. 3) length of extreme IQs is unreliable, that's an obvious bias that may not possible to dazzling for completely... Medians would be lots greater interesting than means for this style of assessment. 4) there are distinctive different themes with IQ assessments, which in spite of the actual undeniable fact that doesn't recommend they are completely invalid, style of makes the stated distinction exceptionally "meh" And as form of a sub-factor to #a million, all of us understand that IQ correlates with academic attainment, and that academic attainment correlates negatively with religiosity, and there is slightly bit study between CAM (complementary and determination drugs) and academic attainment... lots of which, would recommend that Nyborg's hypothesis is exceptionally "meh". --- Like particularly, there is a lot greater effective belongings you ought to confer with theists as antagonistic to this. it particularly is the only reason I replied.
