go to post Vitaliy Serdtsev · Oct 6, 2021 Those experienced with encryption systems for databases may have concerns about encryption having dire effects on performance, but, with Caché, these concerns are unfounded. Encryption and decryption have been optimized, and their effects are both deterministic and small for any Caché platform; in fact, there is no added time at all for writing to the database. Managed Key Encryption: Protecting Data on Disk InterSystems recommends using its encryption management tools: When built-in hardware instructions are available for encryption-related activities, these activities are considerably faster then when using software-based encryption. The encryption management tools use hardware instructions when they are available. The encryption management tools can use keys stored on a KMIP server. The encryption management tools can run in FIPS mode. About Encryption Management Operations High-Performance Encryption for Databases in Financial Services (PDF)
