SSL Clock

SSL Clock is an SSL/TLS certificate monitor for small teams, agencies and MSPs. Add hostnames one at a time, as a pasted list or from a CSV file. SSL Clock connects to each one, reads the certificate the server actually serves and records the issuer, names, chain status and expiry date. You get reminders 30, 14, 7, 3 and 1 day before a certificate expires, or on your own schedule of up to 10 reminder days. An expired certificate, a hostname mismatch, a broken chain, a failed TLS handshake or a host that stops answering triggers an alert from the check that finds it. Every alert explains the likely cause and the fix in plain English, so anyone on the team can act on it. Alerts go to email (you and up to 5 more people), Slack, Microsoft Teams, signed webhooks and PagerDuty, and each site can have its own destinations. SSL Clock also tells you when a site starts serving a different certificate, watches Certificate Transparency logs daily for new certificates issued for your hostnames, and checks domain registration expiry daily. Every plan, including Free, includes the REST API, bulk import, CSV export, a public status page and every alert channel. Paid plans add monitors and team seats, and Pro and Business check every hour instead of every 6 hours. There is nothing to install: no agents and no private keys. Free covers 3 hostnames with no card. Starter is $9 a month for 25, Pro is $29 a month for 150 and Business is $69 a month for 500. Annual billing gives two months free.

The Data Krypter

The easy way to keep your data secure well into the future when quantum computers become mainstream. -encrypts files, folders and blocks of text -when encrypting a file/folder, you can: - -give the file/folder a random name - -securely erase the original -makes your data useless to an attacker in case you are ever a victim of ransomware. But you need to prepare ahead of time by encrypting your sensitive files. Then the attacker cannot: - -use your data or - -threaten to make your files public -you can receive encrypted files from someone else and only one of you needs to have a paid version (or a non-expired trial version) of the Data Krypter. i.e. an accountant or lawyer pays for the software and all their clients can send encrypted files with a trial version (even if it has expired). -even if someone has access to your computer they can't decrypt your files because your: - -master password is encrypted - -private keys are encrypted - -secret keys are encrypted (stored only to help recover keys). -recovery any lost keys or master password with the Data Recovery module <== NEW -symmetric encryption (the same secret key to encrypt and decrypt) using PERNG -asymmetric encryption (public/private keys) using NTRU-2x2 -both types of encryption are quantum proof -send encrypted emails by encrypting the text then pasting it into an email -no back door
