security::csp::nonce (public)
security::csp::nonce [ -tokenname tokenname ]
Defined in packages/acs-tcl/tcl/security-procs.tcl
Generate a nonce token and return it. The nonce token can be used in content security policies (CSP2) for "script" and "style" elements. Desired Properties: generate a single unique value per request which is hard for a hacker to predict, it should only contain base64 characters (so hex is fine). For details, see https://www.w3.org/TR/CSP/
