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.

name

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

iv

An ArrayBuffer, a TypedArray, or a DataView. 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).

See the examples for SubtleCrypto.encrypt() and SubtleCrypto.decrypt().

• CBC mode is defined in section 6.2 of the NIST SP800-38A standard.
• SubtleCrypto.encrypt().
• SubtleCrypto.decrypt().
• SubtleCrypto.wrapKey().
• SubtleCrypto.unwrapKey().
