TheAesCbcParams dictionary of theWeb Crypto API represents the object that should be passed as thealgorithm parameter intoSubtleCrypto.encrypt(),SubtleCrypto.decrypt(),SubtleCrypto.wrapKey(), orSubtleCrypto.unwrapKey(), when using theAES-CBC algorithm.

Instance properties

name

A string. This should be set toAES-CBC.

iv

AnArrayBuffer, aTypedArray, or aDataView. The initialization vector. Must be 16 bytes, unpredictable, and preferably cryptographically random. However, it need not be secret (for example, it may be transmitted unencrypted along with the ciphertext).

Examples

See the examples forSubtleCrypto.encrypt() andSubtleCrypto.decrypt().

Specifications

Browser compatibility

Browsers that support the "AES-CBC" algorithm for theSubtleCrypto.encrypt(),SubtleCrypto.decrypt(),SubtleCrypto.wrapKey(), orSubtleCrypto.unwrapKey() methods will support this type.
