WPA3 support/docs

[ThomasCr]

Hi,

is WPA3 qrcode possible?

[srowen]

You can encode whatever you want in a QR code. There is no syntax or support for WPA3

[ThomasCr]

but how? I cant find any public documentation for the right syntax.

as example wpa3 is also not documented at your resources

The only hints I found:

After digging deeper in the WPA3_Specification_v3.0.pdf (httXs://www.wi-fi.org/download.php?file=/sites/default/files/private/WPA3_Specification_v3.0.pdf) posted at ui.com, I found the definition:

7.1 URI format
The URI is defined by [7] and formatted by the WIFI-qr ABNF rule:
WIFI-qr = “WIFI:” [type “;”] [trdisable “;”] ssid “;” [hidden “;”] [id “;”] [password “;”] [public-key “;”] “;”
type = “T:” *(unreserved) ; security type
trdisable = “R:” *(HEXDIG) ; Transition Disable value
ssid = “S:” *(printable / pct-encoded) ; SSID of the network
hidden = “H:true” ; when present, indicates a hidden (stealth) SSID is used
id = “I:” *(printable / pct-encoded) ; UTF-8 encoded password identifier, present if the password has an SAE password identifier
password = “P:” *(printable / pct-encoded) ; password, present for password-based authentication
public-key = “K:” *PKCHAR ; DER of ASN.1 SubjectPublicKeyInfo in compressed form and encoded in “base64” as per [6], present when the network supports SAE-PK, else absent
printable = %x20-3a / %x3c-7e ; semi-colon excluded
PKCHAR = ALPHA / DIGIT / %x2b / %x2f / %x3d
.....
7.3 URI examples
Some examples of the WIFI URI format are as follows:

1. WIFI:T:WPA;S:MyNet;P:MyPassword;;
   ▪ STA that supports WPA3-Personal might use SAE or PSK (WPA3-Personal transition mode)
   ▪ STA that does not support WPA3-Personal uses PSK (WPA2-Personal)
2. WIFI:T:WPA;R:1;S:MyNet;P:MyPassword;;
   ▪ STA that supports WPA3-Personal and Transition Disable uses SAE only (WPA3-Personal only mode)
   ▪ STA that supports WPA3-Personal but not Transition Disable might use SAE or PSK (WPA3-Personal
   transition mode)
   ▪ STA that does not support WPA3-Personal uses PSK (WPA2-Personal)
3. WIFI:T:WPA;R:3; S:MyNet;P:a2bc-de3f-ghi4;K:MDkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDIgADURzxmttZoIRIPW
   GoQMV00XHWCAQIhXruVWOz0NjlkIA=;;
   ▪ STA that supports SAE-PK (and, therefore, Transition Disable) uses SAE-PK only (SAE-PK only mode)
   ▪ STA that supports WPA3-Personal and Transition Disable but not SAE-PK uses SAE without SAE-PK only
   (WPA3-Personal only mode)
   ▪ STA that supports WPA3-Personal but not Transition Disable or SAE-PK might use SAE or PSK (WPA3-
   Personal transition mode)
   ▪ STA that does not support WPA3-Personal uses PSK (WPA2-Personal)
4. WIFI:R:4;S:MyNet;;
   ▪ STA that supports Wi-Fi Enhanced Open and Transition Disable uses Wi-Fi Enhanced Open only mode
   ▪ STA that supports Wi-Fi Enhanced Open but not Transition Disable might use Wi-Fi Enhanced Open or
   legacy open (Wi-Fi Enhanced Open transition mode)
   ▪ STA that does not support Wi-Fi Enhanced Open uses legacy open
