Generated iRule (by F5 Distributed Cloud AI Assistant):

    # Retrieve the Authorization header
    set auth_header [HTTP::header "Authorization"]

    # Check if Authorization header exists and starts with "Basic "
    if { $auth_header ne "" && [string tolower [string range $auth_header 0 5]] eq "basic " } {
        # Extract the Base64-encoded token by removing "Basic " prefix
        set b64_token [string range $auth_header 6 end]

        # Attempt to decode the Base64 token safely
        if { [catch {b64decode $b64_token} decoded_creds] == 0 && $decoded_creds ne "" } {
            # Extract username by splitting decoded string at the first colon
            if { [regexp -- {^([^:]+):} $decoded_creds -> username] } {
