Here are some common uses of cryptography:įinancial transactions and online banking: Online banking and ecommerce websites use advanced encryption techniques to keep financial information safe. Protecting data with cryptography helps minimize threats like ransomware attacks, because if hackers intercept information, they won’t be able to understand it without a decryption key. Use of cryptographyĬryptography is used to keep communications and information private. Hashing, another cryptographic process, is not technically encryption, since it doesn’t use keys. Symmetric encryption, asymmetric encryption, blockchain, and digital signatures are some prominent encryption techniques. The exact technique used to scramble plaintext into ciphertext defines how cryptography works. In asymmetric encryption, a public key is used to encrypt a message and a private key is used to decrypt it.

The best encryption software uses complicated cryptographic algorithms that are incredibly difficult to crack.
In cybersecurity, encryption is most often used to scramble plaintext into ciphertext - while decryption reverses the process. As ciphertext, the information should be unreadable to all except the intended recipient. Commonly using the MD5 hashing algorithm, hashing is often used for authentication purposes.Ĭryptography works by taking plaintext (or cleartext) and scrambling it into ciphertext, so that the encoded output can be understood only by the intended recipient. With hash functions, both a one-word message and a 1000-page novel create a fixed-sized output of encoded text (called a hash value), making it nearly impossible to determine the original content. Instead, they scramble data of varying size into values of uniform length. Hash Functions: Hash functions don’t rely on keys. If the message is intercepted, the contents can’t be deciphered without the private key. Public Key Cryptography: The sender uses a public key to encrypt the message, and the receiver uses a private key to decrypt it. If the message is intercepted, the included key can decode its contents.
The sender includes the secret key in the coded message sent to the intended recipient. Secret Key Cryptography: A secret key is used to both encrypt and decrypt the data.
Here are the different types of cryptography:

Most types of cryptography use algorithms called keys that scramble and unscramble, or code and decode, data. There are three cryptography types, which are distinguished by the types of cryptographic algorithms they use to scramble data. 86417811053 Logo Ameba Icon Security Icon Security White Icon Privacy Icon Performance Icon Privacy Icon Security Icon Performance Icons/45/01 Security/Other-Threats Icons / 32 / Bloatware removal Icons / 32 / Registry Cleaner Icons / 32 / CleanUp Icons / Feature / 32 / Mac Icons / 32 / Browser cleanup Icons/32/01 Security/Malware Icons/32/01 Security/Viruses Icons/32/01 Security/Other-Threats Icons/32/01 Security/Passwords Icons/32/01 Security/Ransomware Icons/32/01 Security/Business Icons/32/02 Privacy/Browser Icons/32/02 Privacy/IP adress Icons/32/02 Privacy/VPN Icons/32/02 Privacy/Proxy Icons/32/02 Privacy/Streaming Icons/32/03 Performance/Celaning Icons/32/03 Performance/Drivers Icons/32/03 Performance/Gaming Icons/32/03 Performance/Hardware Icons/32/03 Performance/Speed Icons / 32 / Bloatware removal Icons / 32 / Registry Cleaner Win Icons / 32 / CleanUp Icons / Feature / 32 / Mac Icons / 32 / Browser cleanup Icons/60/02 Privacy/02_Privacy Icons/60/01 Security/01_Security Icons/60/03 Performance/03_Performance Icons/80/01 Security/IoT Icons/80/01 Security/Malware Icons/80/01 Security/Passwords Icons/80/01 Security/Ransomware Icons/80/01 Security/Viruses Icons/80/01 Security/Other-Threats Icons/80/03 Security/Business Icons/80/02 Privacy/Browser Icons/80/02 Privacy/IP adress Icons/80/02 Privacy/VPN Icons/80/02 Privacy/Proxy Icons/80/02 Privacy/Streaming Icons/80/03 Performance/Celaning Icons/80/03 Performance/Drivers Icons/80/03 Performance/Gaming Icons/80/03 Performance/Hardware Icons/80/03 Performance/Speed Icons/80/03 Performance/03_Performance Icons/80/02 Privacy/02_Privacy
