No. If you're after total offload then the crypto API is not for you. What we can support is the offloading of encryption/decryption over many sectors. Cheers,
FMP doesn't use encrypt/decrypt of crypto API because it doesn't expose cipher-text to DRAM. But, Crypto API has many useful features such as cipher management, cipher allocation with cipher name, key management and test manager. All these features are useful for FMP. FMP has been cerified with FIPS as below by using test vectors and test manager of Crypto API. https://csrc.nist.gov/projects/cryptographic-module-validation-program/Certi ficate/3255 https://csrc.nist.gov/CSRC/media/projects/cryptographic-module-validation-pr ogram/documents/security-policies/140sp3255.pdf Can't I use crypto APIs to take advantage of this? I want to find a good way that FMP can use crypto API. Thanks Boojin Kim.
