The combination of our free, lightning-fast and always-on timestamp service and the easy to use cli tool, gets you started in a minute. Everything is built on top of open source components. Every build has a story to tell - Tamperproof provenance for your code and CI/CD pipeline What is trusted timestamping? is the process of securely keeping track of the creation and modification time of a document. Trusted timestamping Security here means that no one—not even the owner of the document—should be able to change it once it has been recorded provided that the timestamper's integrity is never compromised. uses its immutable open source database to provide this service that includes cryptographic verification and immutable data history. CodeNotary immudb CodeNotary Use Cases This timestamping service provides full immutability for all data ever written and unique data checksum ever stored including its history. As a trust level comes with the timestamp, you can change your mind over time (unsupport, untrust) without touching the code or binary. As the complete trust and timestamping history is stored for any digital identity (SHA-256 checksum), you can easily create workflows and decision trees in your CI/CD recipes. There are plenty of different use cases: Add a trusted timestamp to code Add an immutable timestamp to electronic signatures Seal the data integrity and your trust level at a given point in time Prove the existence of elecronic data at a specific point in time CI/CD integration - notarize all outgoing assets, authenticate all incoming Store provenance for you own sources Unsupport deprecated versions of your software and run update checks bases on the latest timestamp Revoke trust (untrust) at any time without the need to touch your code or binaries Trust or remove trust for digital assets and act on the status (within your script or pipeline) Simply timestamp files and sources to doublecheck at any time in the future if these are still the same (backup/restore) Simply request your API key and get started within a minute! This service was built using Open Source and to run free forever! Notarized assets information is stored in a tamperproof ledger with cryptographic verification backed by immudb, the immutable database. Obtain an API Key To provide access to our timestamping service a valid API Key is required. If you don't have one yet, simply signup here . CodeNotary Timestamp This API Key is bound to your email address and it's required during vcn login. Quick start 1. In case you use Linux or macOS, the quickest start is our install script: Installer bash <(curl https: //getvcn.codenotary.com -L) You can also download the latest release 2. to Login timestamp.codenotary.com vcn login --lc-host timestamp.codenotary.com # type your API key when requested # or setting the API key VCN_LC_API_KEY= in < Your-API-Key vcn login --lc-host timestamp.codenotary.com 3. Once you have an account you can start notarizing digital assets to give them an identity. Notarize (Timestamp) existing digital objects vcn n <file|dir: //directory|docker://dockerimage|git://gitdirectory> 4. You can use the command as a starting point. Authenticate digital objects vcn a <file|dir: //directory|docker://dockerimage|git://gitdirectory> : the timestamping and verification calculates a SHA256, so larger files might take a bit longer depending on your system. Tip For detailed , just run . command line usage vcn help Also published at https://dev.to/vchaindz/codenotary-free-trusted-timestamping-service-for-developer-158f
