Is there any reference to check the list of encryption & signing algorithms which are compliant to FIPS 140-2. After an exhaustive search I could find only "AES".
Any suggestions would be much appreciated.
Take a look at FIPS 140-2 Annex A. It lists the following:
The current list of FIPS-approved cryptographical methods is here.
For encryption, we're limited to AES, 3DES (known as TDEA in FIPS-speak), and EES (Skipjack).
As for signing algorithms, we have RSA, DSA and ECDSA.
Note that the list of FIPS-approved algorithms does change at times; not extremely frequently, but more often than they come out with a new version of FIPS 140.
Looks like there is no FIPS 140-2 approved asymmetric encryption algorithm, as DSA/RSA/ECDSA are only approved for key generation/signature.
