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.

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

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.
