Accessors

iv

Set Signature

set iv(iv): void

Specify the initialization vector (IV) to use.

Remarks

This parameter is mandatory.

Parameters

iv

ArrayBuffer

The initialization vector to use.

Returns

void

---

ivSize

Get Signature

get ivSize(): number

Get the size of the initialization vector (IV) for the CBC cipher.

Throws

InvalidArgumentError If the IV has an invalid length.

Returns

number

The size of the IV in bytes.

---

key

Set Signature

set key(key): void

Specify the symmetric key to be used for encryption or decryption.

Remarks

This parameter is mandatory.

Parameters

key

SymmetricKey

The symmetric key to use.

Returns

void

Inherited from

CipherContextBuilder.key

Methods

buildDecryptionContext()

buildDecryptionContext(): DecryptionContext

Build a context that can be used for decryption operations.

Returns

DecryptionContext

A decryption context.

Throws

AccessDeniedError If the key lacks the KeyPurpose.DECRYPT purpose.

Throws

InvalidArgumentError If any mandatory parameter is missing or the key is invalid.

Inherited from

CipherContextBuilder.buildDecryptionContext

---

buildEncryptionContext()

buildEncryptionContext(): EncryptionContext

Build a context that can be used for encryption operations.

Returns

EncryptionContext

An encryption context.

Throws

AccessDeniedError If the key lacks the KeyPurpose.ENCRYPT purpose.

Throws

InvalidArgumentError If any mandatory parameter is missing or the key is invalid.

Inherited from

CipherContextBuilder.buildEncryptionContext

---

buildWrappingContext()

buildWrappingContext(scheme): WrappingContext

Build a context that can be used for wrapping keys.

Parameters

scheme

WrappingScheme

The wrapping scheme to be used.

Returns

WrappingContext

A wrapping context.

Throws

AccessDeniedError If the key lacks the KeyPurpose.WRAP and KeyPurpose.UNWRAP purposes.

Throws

InvalidArgumentError If any mandatory parameter is missing or the key is invalid.

Throws

NotSupportedError If the implementation does not support wrapping operations.
