AesDerivedKeyParams

The AesDerivedKeyParams dictionary of the Web Crypto API represents the object that should be passed as the derivedKeyType parameter into SubtleCrypto.deriveKey(), when deriving an AES key: that is, when the algorithm is identified as any of AES-CBC, AES-CTR, AES-GCM, or AES-KW.

Instance properties

name

A string. This should be set to AES-CBC, AES-CTR, AES-GCM, or AES-KW, depending on the algorithm you want to use.

length

A Number — the length in bits of the key to generate. This must be one of: 128, 192, or 256.

Examples

See the examples for SubtleCrypto.deriveKey().

Specifications

• Web Cryptography Level 2

Browser compatibility

Browsers that support any of the AES-based algorithms for the SubtleCrypto.deriveKey() method will support this type.
