KMS integration # KMS plays an important role for providing cryptographic keys security. Currently, Acra uses KMS to load Acra Master Key used for intermediate keys encrypting / decrypting. Since safety of Acra’s cryptographic keys directly depends on safety of Acra Master Key, Acra has strong requirements to KMSs and their security guarantees. Refer to Acra in depth / Key storage and KMS to learn more about general key storage requirements.
