Report factors
Paste a whole factor list - an .elf file, GMP-ECM output, or plain
N = f1 * f2 * … lines. Each number is found together with its factors; the ones
that actually divide are submitted and the rest ignored. Numbers at or below 1018
are skipped (they are computed on demand and never stored).
Upload primality certificates
Upload one or more certificates, or a .zip batch (expanded here in the browser
request - the core is handed one certificate at a time). The number a certificate proves is
read from the certificate itself. A number under 300 digits is proved locally and its upload
is declined; an existing certificate is kept and the upload ignored; a certificate is only
removed if verification fails.
