The encryption key is safe to distribute, the decryption key is kept private. The basic idea is that two keys are generated, one for encrypting and one for decrypting. Perhaps the most ingenious and influential development in modern cryptography is the asymmetric key pair, also referred to as public-private key pairs. Most crypto libraries include facilities for these generators. More secure means of generating random numbers have been developed to foil random number attacks. Indeed, the story of cryptography is one of back and forth jockeying, a kind of call and response of innovation. The ingenuity of hackers seems to keep pace with that of white hat coders. If a hacker knows how the numbers are generated, they could devise random number attacks. Most types of random seeding (like pulling from the system clock) are only “sort of” random. (Often, user supplied input is also incorporated, but humans are notoriously unreliable in providing such input.) That depends on generating random numbers. Why is that? Simply put, any secret communication system depends on values that are known to the securing party, and unknown to the outside. Pseudo-random functionsĪlong with one-way functions, algorithms for generating random-like numbers are considered cryptographic “primitives,” i.e., fundamental building blocks necessary for securing communications. As long as the salt is kept secret, passwords hashed with it are basically uncrackable.įor a succinct understanding of the theory behind one-way hashing, take a look at this Stack Overflow answer.

Modern hashing libraries include the capability to increase the difficulty of the hash (thereby allowing the hash strength to increase as computing power increases) and to introducing “salt” into the algorithm (thereby ensuring that hashes of identical inputs are nevertheless unique). That said, one-way hashing is not perfect and a variety of techniques have been introduced for cracking them (like Rainbow tables).

It’s a curious fact to observe that even though attackers have full access to the logic of the algorithm (for example, here’s the source for BCrypt), they are generally unable to reverse the function. There is no known method (using current computer systems) to efficiently reverse the process. Even if an attacker gains access to the database, the passwords are secure.

The password is taken from plain text (“fluffy123”) and the one-way algorithm turns it into a random-looking string (“XFcbe2d3bh0sa”). Like the name suggests, a one-way function works in only one direction.Ī common use for one-way functions, and a good way to understand them, is hashing passwords when they are persisted to the database (for instance, in Java and in JavaScript). One-way functions are considered a cryptographic primitive. Many new techniques arose, but among the most fundamental is what is known as a one-way function (which includes one-way hashes, for generating fixed-length output). With the advent of computers and attendant advancements in mathematics, the possibilities of encryption grew more complex. This necessity implies all sorts of logistical weaknesses.Ī famous example of a symmetric cipher is the Enigma machine employed during WWII. Such a key must be distributed to all participating parties. More secure is creating a complex mapping that requires a key for translation.

Shifting four places in the alphabet is very obvious, and not secure. These processes are called encryption and decryption. Decoding then would involve simply subtracting four from each letter. For instance, a simple cipher would be to add four to every letter in the text (so A becomes E). A cipher is a mapping from readable text to gibberish, and back again. Non-repudiation: Communication can be confirmed, and not later denied by participants.Ĭryptography before the advent of computers relied on the use of ciphers.Authentication: Parties are able to reliably verify each other’s identity.Integrity: Data is not manipulated or destroyed.Confidentiality: Data is not exposed to unintended parties.

The discipline of cryptography can be described as having four aspects: This is achieved using a variety of techniques that boil down to implementing protocols that prevent unwelcome parties from viewing or altering data. What is cryptography?Ĭryptography is the practice of securing communications.

Every time you log into an app or send an email, you are relying on an ingenious cryptographic infrastructure that is descended largely from breakthroughs in the 1970s.īeyond just specialist software developers, beyond just coders, even the non-programming general public can benefit from understanding how cryptography works, especially in an age of crypto currency and crypto investment.Īll of us use cryptography in our daily lives, whether we know it or not. Cryptography grows ever more prominent in our lives.
