No More Ransom is a project focused on reducing the impact of ransomware attacks by providing freely available software that can decrypt files of various ransomware implementations. [ 1 ] [ 2 ] The project is supported by the Dutch National Police Corps and Europol .

LEA is free for any use: public or private, commercial or non-commercial. The source code for distribution of LEA implemented in C, Java, and Python can be downloaded from KISA's website. [6] In addition, LEA is contained in Crypto++ library, a free C++ class library of cryptographic schemes. [7]
Camellia is a Feistel cipher with either 18 rounds (when using 128-bit keys) or 24 rounds (when using 192- or 256-bit keys). Every six rounds, a logical transformation layer is applied: the so-called "FL-function" or its inverse.
Free and open-source software portal; Scapy is a packet manipulation tool for computer networks, [3] [4] originally written in Python by Philippe Biondi. It can forge or decode packets, send them on the wire, capture them, and match requests and replies.
The idea is to prevent the covert decryption of data. In particular, transparent decryption protocols allow a user Alice to share with Bob the right to access data, in such a way that Bob may decrypt at a time of his choosing, but only while simultaneously leaving evidence for Alice of the fact that decryption occurred.
ProVerif is a software tool for automated reasoning about the security properties of cryptographic protocols. The tool has been developed by Bruno Blanchet and others. Support is provided for cryptographic primitives including: symmetric & asymmetric cryptography; digital signatures; hash functions; bit-commitment; and signature proofs of ...
The decryption uses N, A, C, and T as inputs and produces either P or signals verification failure if the message has been altered. Nonce and tag have the same size as the key K (k bits). [6] In the CAESAR submission, two sets of parameters were recommended: [6]
