WebJun 28, 2024 · Hard problems in cryptography Hardness assumptions on mathematical problems lie at the heart of modern cryptography; they are often what ensure one cannot break an encryption scheme. A key in cryptography is a piece of information, usually a string of numbers or letters that are stored in a file, which, when processed through a cryptographic algorithm, can encode or decode cryptographic data. Based on the used method, the key can be different sizes and varieties, but in all cases, the strength of the encryption relies on the security of the key being maintained.
