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
The private key to use for decryption.
Returns
A decryption context.
Throws
AccessDeniedError If the key lacks the KeyPurpose.DECRYPT purpose.
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
The public key to use for encryption.
Returns
An encryption context.
Throws
AccessDeniedError If the key lacks the KeyPurpose.ENCRYPT purpose.
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
The public key. Required for wrapping operations.
privKey
The private key. Required for unwrapping operations.
scheme
The wrapping scheme to be used.
Returns
A wrapping context.
Throws
AccessDeniedError Thrown when:
- A public key is provided but the key lacks the KeyPurpose.WRAP purpose.
- A private key is provided but the key lacks the KeyPurpose.UNWRAP purpose.
Throws
NotSupportedError If the implementation does not support wrapping operations.
