SHA-3 (Secure Hash Algorithm 3) is a family of cryptographic hash functions
  standardized in NIST FIPS 202, first published in 2015. It is based on the
  Keccak algorithm.
  - EVP_sha3_224(), EVP_sha3_256(), EVP_sha3_384(),
    EVP_sha3_512()
- The SHA-3 SHA-3-224, SHA-3-256, SHA-3-384, and SHA-3-512 algorithms
      respectively. They produce 224, 256, 384 and 512 bits of output from a
      given input.
- EVP_shake128(), EVP_shake256()
- The SHAKE-128 and SHAKE-256 Extendable Output Functions (XOF) that can
      generate a variable hash length.
    Specifically, EVP_shake128 provides an overall security
        of 128 bits, while EVP_shake256 provides that of 256 bits. 
Developers should be aware of the negative performance implications of calling
  these functions multiple times and should consider using
  EVP_MD_fetch(3) with EVP_MD-SHA3(7) or EVP_MD-SHAKE(7)
  instead. See "Performance" in crypto(7) for further
  information.
These functions return a EVP_MD structure that contains the
  implementation of the message digest. See EVP_MD_meth_new(3) for
  details of the EVP_MD structure.
