CONFIG_SUNRPC_DISABLE_INSECURE_ENCTYPES: Secure RPC: Disable insecure Kerberos encryption types

General informations

The Linux kernel configuration item CONFIG_SUNRPC_DISABLE_INSECURE_ENCTYPES:

• prompt: Secure RPC: Disable insecure Kerberos encryption types
• type: bool
• depends on: CONFIG_RPCSEC_GSS_KRB5
• defined in net/sunrpc/Kconfig
• found in Linux kernels: 5.3–5.19, 6.0–6.2, 6.2+HEAD

Help text

Choose Y here to disable the use of deprecated encryption types with the Kerberos version 5 GSS-API mechanism (RFC 1964). The deprecated encryption types include DES-CBC-MD5, DES-CBC-CRC, and DES-CBC-MD4. These types were deprecated by RFC 6649 because they were found to be insecure.

N is the default because many sites have deployed KDCs and keytabs that contain only these deprecated encryption types. Choosing Y prevents the use of known-insecure encryption types but might result in compatibility problems.
