Secret value type

A simple implementation of a secure and serializable (serde and proto) type of any kind of secrets: - Automatically cleaning up its value after destruction in memory using zeroize - Prevents leaking in logs and stack traces - Stored as a byte array and suitable not just for string typed secrets - Introduces additional functions with predicates to control the exposed border of exposed secret values and clean-ups: exposed_in_*.

Working with the type:

```rust use secretvaultvalue::*;

let secret_value = SecretValue::from("test"); // Use secret_value.ref_sensitive_value() ```

Quick start

Cargo.toml: toml [dependencies] secret-vault-type = { version = "0.2.<x>", features=["..."] } See security consideration below about versioning.

Available optional features for secret value type:

• serde for serde serialization support
• prost for protobuf serialization support
• bytes for bytes conversion support

Security considerations and risks

OSS

Open source code is created through voluntary collaboration of software developers. The original authors license the code so that anyone can see it, modify it, and distribute new versions of it. You should manage all OSS using the same procedures and tools that you use for commercial products. As always, train your employees on cyber security best practices that can help them securely use and manage software products. You should not solely rely on individuals, especially on the projects like this reading sensitive information.

Versioning

Please don't use broad version dependency management not to include a new version of dependency automatically without your auditing the changes.

Protect your secrets in GCP/AWS using IAM and service accounts

Don't expose all of your secrets to the apps. Use IAM and different service accounts to give access only on as-needed basis.

Zeroing, protecting memory and encryption don't provide 100% safety

There are still allocations on the protocol layers, there is a session secret key available in memory, privileged users on OS still have broad access, etc. So don't consider this is a completely safe solution for all possible attacks. Mitigation some of the attacks is not possible without implementing additional support on hardware/OS level (such as Intel SGX project, for instance).
