Remember that the IV is not secret, but it should still have the properties as described in Squeamish Ossifrage's answer. In the file you want to use the encrypt and decrypt, use import the code like as follows. Cheers. 52. Blob encryptedData = Crypto.encryptWithManagedIV('AES128',blob.valueOf('secrettoencrypt1'),data); Blob decryptedData = Crypto.decryptWithManagedIV('AES128',blob.valueOf('secrettoencrypt1'),encryptedData); I managed to find a way to use the same secretkey in the encryption function. And using documentation I have write down the below function but it al;ways gives error IV must be 16 bytes long but I am using 16 byte long IV. If key__c == 'abcdefghijklmnop', then it's not 16 bytes when decoded. The IV length in terms of the number of bits or bytes depends on the encryption method. Will all turbine blades stop moving in the event of a emergency shutdown. Already on GitHub? The recipient can also discover the IV by calculating it incrementally or by measuring parameters like current time, using the sender's or recipient's address, or by using the packet or cluster number.
