CONFIG_CRYPTO_USER_API_AEAD: AEAD cipher algorithms (deprecated)

General informations

The Linux kernel configuration item CONFIG_CRYPTO_USER_API_AEAD has multiple definitions:

AEAD cipher algorithms (deprecated) found in crypto/Kconfig

The configuration item CONFIG_CRYPTO_USER_API_AEAD:

• prompt: AEAD cipher algorithms (deprecated)
• type: tristate
• depends on: CONFIG_NET
• defined in crypto/Kconfig
• found in Linux kernels: 7.2-rc+HEAD
• modules built: algif_aead

Help text

Enable the AF_ALG userspace interface for authenticated encryption with associated data (AEAD) algorithms. This provides unprivileged userspace programs access to arbitrary AEAD algorithms implemented in the kernel's privileged execution context.

This interface is deprecated and is supported only for backwards compatibility. It regularly has vulnerabilities, and the capabilities it provides are redundant with userspace crypto libraries.

Enable this only if needed for support for a program that hasn't yet been converted to userspace crypto, for example iwd.
