mbedtls@3

brew install mbedtls@3 v3.6.6 Apache-2.0 keg-only

Cryptographic & SSL/TLS library implementing TLS, DTLS, and X.509 certificate handling (version 3.x)

Why you might care

Lightweight alternative to OpenSSL for embedded systems and applications requiring minimal dependencies. Used as a build/runtime dependency in projects needing standards-compliant TLS without the complexity of larger crypto libraries. Supports PSA Cryptography API for portable cryptographic operations.
