Memory Hole

Protected E-Mail Headers.

Encrypted or signed e-mail does not have cryptographic protection of headers; only the body of an e-mail message is encrypted or signed.

The Memory Hole project aims to fix this problem by stashing relevant headers within the body of the e-mail in a standardized way. Compatible mail user agents should be able to use this structure to display the cryptographically protected headers to the user, indicating their protection.


Development of the Memory Hole project takes place on GitHub.
