One-Call function for Fapi_VerifySignature
Verifies a signature using a public key found in a keyPath.
- Parameters
-
| [in,out] | context | The FAPI_CONTEXT |
| [in] | keyPath | The path to the verification public key |
| [in] | digest | The that was signed. Must be already hashed |
| [in] | digestSize | the size of digest in bytes |
| [in] | signature | The signature to be verified |
| [in] | signatureSize | The size of signature in bytes |
- Return values
-
| TSS2_RC_SUCCESS | if the function call was a success. |
| TSS2_FAPI_RC_BAD_REFERENCE | if context, keyPath, signature, or digest is NULL. |
| TSS2_FAPI_RC_BAD_CONTEXT | if context corruption is detected. |
| TSS2_FAPI_RC_KEY_NOT_FOUND | if keyPath does not map to a FAPI object. |
| TSS2_FAPI_RC_BAD_KEY | if the object at publicKeyPath is not a key, or is a key that is unsuitable for the requested operation. |
| TSS2_FAPI_RC_BAD_VALUE | if signature is invalid (has the wrong format) or if digestSize is zero. |
| TSS2_FAPI_RC_SIGNATURE_VERIFICATION_FAILED | if the signature fails to verify. |
| TSS2_FAPI_RC_BAD_SEQUENCE | if the context has an asynchronous operation already pending. |
| TSS2_FAPI_RC_IO_ERROR | if the data cannot be saved. |
| TSS2_FAPI_RC_MEMORY | if the FAPI cannot allocate enough memory for internal operations or return parameters. |
| TSS2_FAPI_RC_PATH_NOT_FOUND | if a FAPI object path was not found during authorization. |
| TSS2_FAPI_RC_TRY_AGAIN | if an I/O operation is not finished yet and this function needs to be called again. |
| TSS2_FAPI_RC_GENERAL_FAILURE | if an internal error occurred. |
| TSS2_FAPI_RC_NOT_PROVISIONED | FAPI was not provisioned. |
| TSS2_FAPI_RC_BAD_PATH | if the path is used in inappropriate context or contains illegal characters. |

| [in] | signatureSize | The size of signature in bytes |
- Return values
-
| TSS2_RC_SUCCESS | if the function call was a success. |
| TSS2_FAPI_RC_BAD_REFERENCE | if context, keyPath, signature, or digest is NULL. |
| TSS2_FAPI_RC_BAD_CONTEXT | if context corruption is detected. |
| TSS2_FAPI_RC_KEY_NOT_FOUND | if keyPath does not map to a FAPI object. |
| TSS2_FAPI_RC_BAD_KEY | if the object at publicKeyPath is not a key, or is a key that is unsuitable for the requested operation. |
| TSS2_FAPI_RC_BAD_VALUE | if signature is invalid (has the wrong format) or if digestSize is zero. |
| TSS2_FAPI_RC_SIGNATURE_VERIFICATION_FAILED | if the signature fails to verify. |
| TSS2_FAPI_RC_BAD_SEQUENCE | if the context has an asynchronous operation already pending. |
