Cryptography is the practice and study of encrypting information, or in other words, securing information from unauthorized access. There are many different cryptography laws in different nations. Some countries prohibit the export of cryptography software and/or encryption algorithms or cryptoanalysis methods. Some countries require decryption ...
In colloquial use, the term "code" is often used to mean any method of encryption or concealment of meaning. However, in cryptography, code has a more specific meaning: the replacement of a unit of plaintext (i.e., a meaningful word or phrase) with a code word (for example, "wallaby" replaces "attack at dawn").

The purpose is to allow access to material for confiscation or digital forensics purposes and use it either as evidence in a court of law or to enforce national security interests.
Cryptography allows digitals assets to be transacted and verified without the need for a trusted third party.
Countries may wish to restrict import of cryptography technologies for a number of reasons: Imported cryptography may have backdoors or security holes (e.g. the FREAK vulnerability), intentional or not, which allows the country or group who created the backdoor technology, for example the National Security Agency (NSA), to spy on persons using the imported cryptography; therefore the use of ...
Key escrow (also known as a "fair" cryptosystem) [citation needed] is an arrangement in which the keys needed to decrypt encrypted data are held in escrow so that, under certain circumstances, an authorized third party may gain access to those keys.
Human rights and encryption are often viewed as interlinked.Encryption can be a technology that helps implement basic human rights. In the digital age, the freedom of speech has become more controversial; however, from a human rights perspective, there is a growing awareness that encryption is essential for a free, open, and trustworthy Internet.
Cryptocurrency is a type of digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments, like dollars or euros, cryptocurrencies operate on ...
