6.4 Get Locking Key

The getLockingKeyFor:keyGenerationPolicy:groupId:success:failure function of BayunCore class returns locking key along with the keys for signature generation and signature verification for an encryption policy.

The function takes the following parameters :

• encryptionPolicy : BayunEncryptionPolicy determines the key to be used to generate the lockingKey.

• keyGenerationPolicy : BayunKeyGenerationPolicy determine the policy to be used to generate the lockingKey.

• groupId: GroupId is required if encryptionPolicy is BayunEncryptionPolicyGroup. If encryption-policy is other than BayunEncryptionPolicyGroup then groupId should be empty string.

Objective-C

 BayunEncryptionPolicy encryptionPolicy = BayunEncryptionPolicyCompany;
 BayunKeyGenerationPolicy keyGenerationPolicy = BayunKeyGenerationPolicyStatic;
 [[BayunCore sharedInstance] getLockingKeyFor:encryptionPolicy keyGenerationPolicy:keyGenerationPolicy groupId:nil success:^(LockingKeys *lockingKeyInfo) {
   NSString *key = lockingKeyInfo.key;      
 } failure:^(BayunError error) {
   NSLog(@"Error in Key Generation.");            
 }];

Swift

 let encryptionPolicy : BayunEncryptionPolicy = .company
 let keyGenerationPolicy : BayunKeyGenerationPolicy = .static
 BayunCore.sharedInstance()?.getLockingKey(for:encryptionPolicy, keyGenerationPolicy: keyGenerationPolicy, groupId: "", success: { (lockingKeysInfo) in
   let lockingKey = lockingKeysInfo?.key!
 }, failure: { (error) in
   NSLog("Error in Key Generation.")
 })
