|
ECC
|
|
|
DSA
|
|
|
DH
|
|
|
HMAC

Explanation:
Detailed explanation-1: -The U.S. federal government requires the use of DSA, RSA or Elliptic Curve DSA and SHA for digital signatures. DSA is slower than RSA and only provides digital signatures. RSA provides digital signatures, encryption, and secure symmetric key distribution.
Detailed explanation-2: -El Gamal-Extension of the Diffie-Hellman key exchange. Since El Gamal did not obtain a patent, it is freely available for use unlike the then-patented RSA technology.
