    strobe

    STROBE cryptographic protocol framework

    Note: this is alpha-quality software, and isn't ready for production use. STROBE is a lightweight framework for cryptographic protocols. It supports encryption/decryption, hashing, pseudorandom generation and message authentication. It integrates these components in an innovative way that makes secure protocol design relatively simple. With the included elliptic curve code, STROBE additionally supports asymmetric key exchange and digital signature creation and verification.

    Split your file into encrypted fragments

    Horcrux is a command-line tool built in Go that enables you to split a file into encrypted fragments (“horcruxes”) so you don’t need to remember a pass-code for later decryption. It uses the Shamir Secret Sharing scheme to break an encryption key into multiple pieces, such that only a threshold of them can reconstruct the original file. You select the number of fragments to create and the minimum number required to recover the file, then scatter the fragments (e.g., on USBs or cloud...
