6 Supported mask generation functions: MGF1 with SHA-1, RIPEMD-160, SHA-224, SHA-256, SHA-384, SHA-512. The MGF hash function must be the same as the data hash function.
7 Imported keys can use any parameters. The key generation will use the following specific parameters:
- 2048/224/SHA224 and 2048/256/SHA256: [KISA]
* Hash algorithms not listed as a supported “Cryptographic hash function” on this page can only be used in signature generation/verification with prehashed data.
