Best Practices for Encrypting Legacy Messages

Learn effective strategies for encrypting legacy messages, ensuring long-term security and compliance against evolving threats.

Best Practices for Encrypting Legacy Messages

Legacy messages - sensitive communications meant for future delivery - require strong encryption to remain secure over time and accessible to the right people. Here’s what you need to know:

  • Challenges: Encryption must withstand technological advances like quantum computing, while key management must ensure security and accessibility for decades.
  • Recommended Tools: Use AES-256 for symmetric encryption, RSA-4096 or ECC for asymmetric encryption, and SHA-512 for hashing.
  • ...
