手順
-
On the Crypto Specifications tab, select New.
-
Complete the Algorithm Definition form.
See Cryptographic specification overview for details.
The algorithm definition screen opens. Select options for the key generation. Repeat this step to generate multiple keys for the selected crypto module.
表 : 1. Algorithm Definition fields Field Crypto module Read only. Name of the selected cryptographic module displays. Crypto purpose Select the purpose of this module. For example, you might use it for data encryption, signature generation, or key wrapping. The available algorithms adjust based on the selected crypto purpose. See Cryptographic specification overview for details. Algorithm Type of algorithm used to accomplish the crypto purpose. The algorithm also controls the key origin. Adjusts automatically based on the selected crypto purpose. Cryptographic specification overview for details. Operation mode This field may display based on the selected crypto purpose. Size Select the bit size. Hash This field becomes available based on the algorithm selected. Equality preserving Enables non-deterministic encryption.
This option appears when you select Symmetric Data Encryption/Decryption with AES and in Cipher Block Chaining (CBC) mode.
Selecting this option means that if the same data is encrypted again the encoded data is the same each time. Non-deterministic encryption doesn’t support filtering a list of encrypted data using equality comparison operators.
Integrity GCM operation mode provides Integrity.
