Problem Statement

Id like the Claude.md to be more secure and not saved plain text.
If I have security protocols that Claude needs to know, there is no way to intrinsically secure them.
If I then have an intruder acting as me, they will see any security plans etc

Proposed Solution

Anthropic publishes a public key. You encrypt CLAUDE.md with it. Only Anthropic's servers (holding the private key) can decrypt it before injecting it as context.

[Encrypted CLAUDE.md on disk]
↓ unreadable to anyone local
[Claude Code sends ciphertext to Anthropic]
↓ Anthropic decrypts server-side
[Plaintext loaded into context — never touches your disk]
Attacker gets the file → gets ciphertext → useless without Anthropic's private key.
