- totp-key-uri SECRET LABEL #!key (issuer #f) (algorithm 'sha1) (digits 6) (period 30)procedure
Builds an otpauth://totp/... provisioning URI for SECRET and LABEL (typically an account name or email address), following the informal but universal "Key Uri Format" convention used by authenticator apps for QR-code-based enrollment. If issuer is given, it is included as the issuer query parameter. All percent-encoding of LABEL, issuer, and the query string is delegated to uri-common's make-uri/uri->string.
