Cryptography is a powerful tool that allows us to protect our sensitive data from unwanted access and manipulation. In this blog post, we’re going to demystify cryptography and explain how mathematics is used to protect our data.
To understand how mathematics protects our data, first we need to understand what cryptography is. Cryptography is the science of secure communication. It is used to protect data by encrypting it into an unreadable form that can’t be accessed without a secret key. Cryptography uses mathematical algorithms, called ciphers, to encrypt and decrypt data.
There are several types of ciphers used in cryptography, but the most commonly used is the symmetric key cipher. This type of cipher uses a single, secret key to both encrypt and decrypt data. The key is shared between parties, and it is used to transform the data into an unreadable form. The data is then safe from unauthorized access and manipulation.
The other type of cipher used in cryptography is the public key cipher. This type of cipher uses two keys, one public and one private, to encrypt and decrypt data. The public key is shared with the public, while the private key is kept secret. The public key is used to encrypt the data, while the private key is used to decrypt it.
Cryptography is an essential part of keeping our data secure. It allows us to protect our data from unauthorized access and manipulation, as well as ensuring that our data remains confidential. By understanding how mathematics is used to protect our data, we can ensure that our data is secure and that our confidential information is kept safe.
