- C_DigestInit(), C_DigestFinal()
- Note
- Digest parameters are shared by a session. Calling C_DigestInit(), C_DigestUpdate(), and C_DigestFinal() with the same session across different tasks may lead to unexpected results.
- Parameters
-
[in] | hSession | Handle of a valid PKCS #11 session. |
[in] | pPart | Pointer to the data to be added to the digest. |
[in] | ulPartLen | Length of the data located at pPart. |
- Returns
- CKR_OK if successful.
