Builds contexts for RSA encryption using OAEP (Optimal Asymmetric Encryption Padding).

Extends

Accessors

digestAlgorithm

Set Signature

set digestAlgorithm(digest): void Specify the digest algorithm to use.
Throws
InvalidArgumentError If the digest algorithm is not supported.
Parameters
digest
DigestAlgorithm The digest algorithm to use with RSA-OAEP.
Returns
void

Methods

buildDecryptionContext()

buildDecryptionContext(key): DecryptionContext Build a decryption context using the given private key. This context can be used to decrypt data that was encrypted with the corresponding public key.

Parameters

key
PrivateKey The private key to use for decryption.

Returns

DecryptionContext A decryption context.

Throws

AccessDeniedError If the key lacks the KeyPurpose.DECRYPT purpose.

Inherited from

AsymmetricCipherContextBuilder.buildDecryptionContext

buildEncryptionContext()

buildEncryptionContext(key): EncryptionContext Build an encryption context using the given public key. This context can be used to encrypt data that only the holder of the corresponding private key can decrypt.

Parameters

key
PublicKey The public key to use for encryption.

Returns

EncryptionContext An encryption context.

Throws

AccessDeniedError If the key lacks the KeyPurpose.ENCRYPT purpose.

Inherited from

AsymmetricCipherContextBuilder.buildEncryptionContext

buildWrappingContext()

buildWrappingContext(pubKey, privKey, scheme): WrappingContext Build a wrapping context using the given public/private key and wrapping scheme. This context can be used for key wrapping operations, which involve encrypting cryptographic keys.

Parameters

pubKey
PublicKey The public key. Required for wrapping operations.
privKey
PrivateKey The private key. Required for unwrapping operations.
scheme
WrappingScheme The wrapping scheme to be used.

Returns

WrappingContext A wrapping context.

Throws

AccessDeniedError Thrown when:

Throws

NotSupportedError If the implementation does not support wrapping operations.
