AesCbcParams - Web APIs 编辑

The AesCbcParams dictionary of the Web Crypto API represents the object that should be passed as the algorithm parameter into SubtleCrypto.encrypt(), SubtleCrypto.decrypt(), SubtleCrypto.wrapKey(), or SubtleCrypto.unwrapKey(), when using the AES-CBC algorithm.

Properties

name

A DOMString. This should be set to AES-CBC.

iv

A BufferSource. 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 for SubtleCrypto.encrypt() and SubtleCrypto.decrypt().

Specifications

Browser compatibility

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