# Cryptography

Glesys applies cryptographic controls for protecting sensitive information and communications.

### Key elements:

* **Encryption standards:** Data in transit protected using TLS (minimum TLS 1.2+) and sensitive data protected with strong encryption (e.g., AES-256 or equivalent) where applicable.
* **Key management:** Keys are managed securely, rotated at least annually or after suspected compromise, and protected from plaintext storage in code or configurations.
* **Hashing/signatures:** Approved hashing algorithms (e.g., SHA-256+) and prohibition of weak algorithms (e.g., MD5/SHA-1).

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.glesys.com/security/security-measures/cryptography.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
