    Naeon

    Naeon

    The safest way to store private data in untrusted (cloud) environments

    Naeon secures data in untrusted off-site storage through a layered approach: files are compressed, then AES-256 encrypted with a randomly generated 128-character passphrase yielding approximately 762 bits of entropy — far beyond the reach of both classical and quantum brute-force attacks. The ciphertext is obfuscated by prepending and appending random byte blocks, making the result unidentifiable as an encrypted file. The payload is then sharded into one private chunk — holding the...

    Vigen

    Vigen

    UTF-8 Multi-pass Tableau de Vigenère Encryption Rotation Engine

    ...Vigen can generate exceedingly strong rotation cyphers that are probably unbreakable without the given keys and tables. Vigen might even generate military grade cyphers, although I make no claim as to the security of the cypher. Vigen is for encrypting UTF-8 TEXT files; it is not intended for encrypting binary files. Vigen is not a private/public key encryption system such as PGP (at least, not yet).

    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

    PureBasic Shamir Secret Sharing

    PureBasic Shamir Secret Sharing

    Open-source PureBasic implementation of the Shamir Secret Sharing

    PureBasic Shamir Secret Sharing is an open-source, self-contained and educational implementation of the Shamir Secret Sharing Scheme, written entirely in PureBasic. Shamir Secret Sharing is a cryptographic method that splits a secret into multiple parts (shares), such that any combination of at least T shares can reconstruct the original secret, while any number of shares fewer than T reveals no usable information. This implementation operates over the finite field GF(257), allowing...

    EasyJCE

    Provides encryption & password hashing for your app or Hibernate POJOs

    EasyJCE provides an easy to use interface for encrypting, decrypting, and hashing data for transmission or storage using the Java Cryptographic Extension (JCE). A set of Hibernate user types is included to transparently integrate encryption into the data layer in a JPA/Hibernate environment, ensuring data is persisted in its encrypted form while obscuring encryption and decryption logic from application code. EasyJCE supports most algorithms implemented for the JCE, including those provided...

Version 7 has been reduced to a simple non secure random number generator and hashing function. If you need high quality random numbers or a 512 bit hash with a small code footprint in an 8 bit environment, Eris 7 may be a good choice, at least the AI's say so.
