Joseph Gresock commented on NIFI-8445:
--------------------------------------
I believe the analogous Spring Vault method would be
[encrypt|https://docs.spring.io/spring-vault/docs/current/api/org/springframework/vault/core/VaultTransitOperations.html#encrypt-java.lang.String-org.springframework.vault.support.Plaintext-]
rather than
[write|https://docs.spring.io/spring-vault/docs/current/api/org/springframework/vault/core/VaultTemplate.html#write-java.lang.String-java.lang.Object-],
but I notice encrypt does take a Plaintext, which wraps bytes[].

> Key: NIFI-8445
> URL: https://issues.apache.org/jira/browse/NIFI-8445
> Project: Apache NiFi
> Issue Type: Sub-task
> Reporter: Joseph Gresock
> Priority: Minor
>
> Suggest using Spring's VaultTemplate to expose an initial set of
> Vault-related methods that can be later expanded.
> Should take the following configuration:
> # Vault address (e.g., [https://localhost:8200|https://localhost:8200/])
> # TLS configuration (used only if address is https)
> # Properties file location for configuring Vault Authentication Method
> Should expose the initial methods:
> * encrypt(String transitKey, String plainText)
> * decrypt(String transitKey, String cipherText)
> This service should be able to be used initially in the NiFi core code and
> Encrypt-Config tool code, and should eventually be made available to the NiFi
> Registry code.
