Field Detail

keyResolver

public com.microsoft.azure.keyvault.core.IKeyResolver keyResolver

Constructor Detail

BlobEncryptionPolicy

public BlobEncryptionPolicy(com.microsoft.azure.keyvault.core.IKey key,
                    com.microsoft.azure.keyvault.core.IKeyResolver keyResolver)

Initializes a new instance of the BlobEncryptionPolicy class with the specified key and resolver.

If the generated policy is intended to be used for encryption, users are expected to provide a key at the minimum. The absence of key will cause an exception to be thrown during encryption. If the generated policy is intended to be used for decryption, users can provide a keyResolver. The client library will - 1. Invoke the key resolver if specified to get the key. 2. If resolver is not specified but a key is specified, match the key id on the key and use it.

Parameters:

key - An object of type IKey that is used to wrap/unwrap the content encryption key.

keyResolver - The key resolver used to select the correct key for decrypting existing blobs.

Method Detail

getKey

public com.microsoft.azure.keyvault.core.IKey getKey()

Gets the IKey that is used to wrap/unwrap the content key during encryption.

Returns:

An IKey object.

getKeyResolver

public com.microsoft.azure.keyvault.core.IKeyResolver getKeyResolver()

Gets the key resolver used to select the correct key for decrypting existing blobs.

Returns:

A resolver that returns an IKey given a keyId.

setKey

public void setKey(com.microsoft.azure.keyvault.core.IKey key)

Sets the IKey that is used to wrap/unwrap the content key during encryption.

Parameters:

key - An IKey object.

setKeyResolver

public void setKeyResolver(com.microsoft.azure.keyvault.core.IKeyResolver keyResolver)

Sets the key resolver used to select the correct key for decrypting existing blobs.

Parameters:

keyResolver - A resolver that returns an IKey given a keyId.
