- n. The science which studies methods for encoding messages so that they can be read only by a person who knows the secret information required for decoding, called the key; it includes cryptanalysis, the science of decoding encrypted messages without possessing the proper key, and has several other branches; see for example steganography.

“The cryptography is simply not fit for purpose,” security consultant Adam Laurie told the Telegraph.
He also relates his subsequent work in cryptography with Steve Pohlig (the Pohlig-Hellman system) and others.
This approach is the brainchild of Silvio Micali, a professor at the Massachusetts Institute of Technology, and his colleague Ronald L. Rivest, a professor who is well known in cryptography circles as one of the technologists behind the creation of RSA Security, a global Internet security company.
In security terms, he explained, cryptography is classed as a protective counter-measure.
Defenders of PGP and other forms of encryption rallied behind Zimmerman and made his case a cause célèbre, arguing that the expression of ideas in cryptography, like any other form of expression, is protected by the First Amendment.
PyPI package index alone has about 50 'cryptography'-tagged entries.
Characters as Alan Turing, Ron Rivest, Adi Shamir, Leonard Adleman, Phil Zimmermann, Whitfield Diffie e Martin Hellman appear when modern cryptography is described.
At any rate, the asymmetry of one-way functions is a pretty powerful concept in cryptography, as well as other fields, but it’s by no means universal … salient
But you can solve the problem by using public-key cryptography, which is the kind of encryption you see on the Internet.
We need password cryptography, not the re-used ones we tend to type ...
