The MSCHAPv2 standard requires MD4 hashing of the password and it's not possible to use a stronger algorithm. I'm closing this. |
Description of problem: wpa_supplicant only supports MD4 hashes. Version-Release number of selected component (if applicable): wpa_supplicant-0.7.3-8.el6 How reproducible: always Steps to Reproduce: 1. Try to use a hash other than MD4 for the password entry Actual results: /etc/wpa_supplicant/wpa_supplicant.conf only supports MD4 hashes for: password= ---------- Sample: /etc/wpa_supplicant/wpa_supplicant.conf Note: the credentials (identity and password lines) have been scrambled. ctrl_interface=/var/run/wpa_supplicant ap_scan=0 network={ key_mgmt=IEEE8021X eap=PEAP identity="user" password=hash:0ec081f204654910186ebf3b4c79418b eapol_flags=0 } ---------- Expected results: Support for SHA256 (at least) Support for SHA512 (additionally) Additional info: MD4 hash has been considered very insecure for many years.
