JarCastingJackson Crypto
Cryptographic utilities for Jackson.
Usage
To use this package from Maven, include the following dependency in your project:
<dependency>
<groupId>com.meltmedia.jackson</groupId>
<artifactId>jackson-crypto</artifactId>
<version>0.2.0</version>
</dpendency>
Then create a new CryptoModule and register it with your ObjectMapper.
EncryptionService service = ...;
ObjectMapper mapper = ...;
mapper.registerModule(new CryptoModule().addSource(service));
Once this is done, you can use the @Encrypted annotation on your @JsonProperty annotated methods to encrypt them during serialization and decrypt them during deserialization. So, a POJO like the following:
public class Pojo {
protected String secret;
@JsonProperty
@Encrypted
public String getSecret() {
return this.secret;
}
public void setSecret( String secret ) {
this.secret = secret;
}
}
will serialize into JSON like:
{
"secret": {
"salt": "tKD8wQ==",
"iv": "s9hTJRaZn6fxxpA4nVfDag==",
"value": "UZENJOltf+9EZS03AXbmeg==",
"cipher": "aes-256-cbc",
"keyDerivation": "pbkdf2",
"keyLength": 256,
"iterations": 2000
}
}
Example
This project does not yet have its own example project, but you can see an example of using this library in the Dropwizard Crypto example project.
