# SecPolicySetValue Sets a policy’s value. ``` OSStatus SecPolicySetValue(SecPolicyRef policyRef, const SecAsn1Item *value); ``` ## Parameters `policyRef` The policy object whose value you wish to set. `value` The value to be set into the policy object, replacing any previous value. ## Return Value A result code. See [Security Framework Result Codes](/documentation/Security/security-framework-result-codes). ## Discussion A policy’s value is defined and interpreted by the policy. If you are using CSSM, you can specify object-identifier–policy-value pairs as input to the `CSSM_TP_POLICYINFO` function. Use the [`SecPolicyGetOID`](/documentation/Security/SecPolicyGetOID) function to obtain the object identifier (OID) for a policy. Depending on how the policy uses the value, the value can be specific to a transaction. Because some other process might be using this policy object, it is best not to assign a new value to the policy using the same policy object. Instead, obtain a new policy object before assigning a new value to the policy. --- Copyright © 2026 Apple Inc.
