# Policy Manager

### createHashIssuePolicy

```solidity
function createHashIssuePolicy(HashIssuePolicyParams _issueData_) external view returns (bytes32)
```

Create hash that verifier will sign and give it to user for issue policy.

*Generates a hash of the parameters required for the verifier to sign the message and provide the signature to the user for issuing the policy.*

| Name        | Type                                            | Description                                          |
| ----------- | ----------------------------------------------- | ---------------------------------------------------- |
| *issueData* | [HashIssuePolicyParams](#hashissuepolicyparams) | The parameters of the issue policy are to be hashed. |

| Name | Type    | Description                                                                                                           |
| ---- | ------- | --------------------------------------------------------------------------------------------------------------------- |
| \[0] | bytes32 | The hash of the required parameters, which can then be used to generate a signature for the user to issue the policy. |

#### HashIssuePolicyParams

```solidity
struct HashIssuePolicyParams {
  address policyholder;
  string policyId;
  string externalReferenceId;
  string documentHash;
  uint40 coverageStart;
  uint40 coverageEnd;
  uint40 claimRequestUntil;
  uint256 premium;
  uint256 sumInsured;
  uint40 signatureValidUntil;
}
```

### createHashRedeemPolicy

```solidity
function createHashRedeemPolicy(HashRedeemPolicyParams _redeemData_) external view returns (bytes32)
```

Create hash that verifier will sign and give it to user for redeem policy.

*Generates a hash of the parameters required for the verifier to sign the message and provide the signature to the user for redeeming the policy.*

| Name         | Type                                              | Description                                           |
| ------------ | ------------------------------------------------- | ----------------------------------------------------- |
| *redeemData* | [HashRedeemPolicyParams](#hashredeempolicyparams) | The parameters of the redeem policy are to be hashed. |

| Name | Type    | Description                                                                                                            |
| ---- | ------- | ---------------------------------------------------------------------------------------------------------------------- |
| \[0] | bytes32 | The hash of the required parameters, which can then be used to generate a signature for the user to redeem the policy. |

#### HashRedeemPolicyParams

```solidity
struct HashRedeemPolicyParams {
  string policyId;
  uint8 redeemRate;
  uint8 riskCarrierRatio;
  uint40 signatureValidUntil;
}
```
