SHA-3 (Secure Hash Algorithm 3), a subset of the cryptographic primitive family Keccak (/ˈkætʃæk/, or /kɛtʃɑːk/), is a cryptographic hash function designed by Guido Bertoni, Joan Daemen, Michaël Peeters, and Gilles Van Assche, building upon RadioGatún. SHA-3 is a member of the Secure Hash Algorithm family. The SHA-3 standard was released by NIST on August 5, 2015. The reference implementation source code was dedicated to public domain via CC0 waiver.
The Keccak algorithm is the work of Guido Bertoni, Joan Daemen (who also co-designed the Rijndael cipher with Vincent Rijmen), Michael Peeters, and Gilles Van Assche. It is based on earlier hash function designs PANAMA and RadioGatún. PANAMA was designed by Daemen and Craig Clapp in 1998. RadioGatún, a successor of PANAMA, was designed by Daemen, Peeters, and Van Assche, and was presented at the NIST Hash Workshop in 2006.
In 2006 NIST started to organize the NIST hash function competition to create new hash standard, SHA-3. SHA-3 is not meant to replace SHA-2, as no significant attack on SHA-2 has been demonstrated. Because of the successful attacks on MD5 and SHA-0 and theoretical attacks on SHA-1, NIST perceived a need for an alternative, dissimilar cryptographic hash, which became SHA-3.

Talk to me baby, I'm listening
Lay down and tell me what's on your mind
What exactly did he do to make you cry this time
Well, I will be your comforter, I will make it right
He cast a shadow on your heart and I will bring back your light
Come in, I see he's hurt you again, when you are in pain, I'm in pain
That's part of being a friend but this is a special case
I held my feelings back because of him and now I can see it more than ever
I made a big big big, big mistake
I don't mean to disregard your feelings but I think that he's a fool
He don't know how sensitive you are and baby that just ain't cool
I'm just glad, I can be there for you when you need a helping hand
When deep inside my heart from the start I know I should've been your man
Lay down and tell me what's on your mind
What exactly did he do to make you cry this time
Well, I will be your comforter, I will make it right
He cast a shadow on your heart and I will bring back your light
I will comfort, comfort, comfort you
I will comfort, I will comfort you
I will comfort, comfort, comfort you
I will comfort, I will comfort you
I will comfort, comfort, comfort you
I will comfort, I will comfort you
I will comfort, comfort, comfort you
I will comfort, I will comfort you
Lay down and tell me what's on your mind
What exactly did he do to make you cry this time
Well, I will be your comforter, I will make it right
