Cryptography Explained: Why It's Essential for Protecting Your Data 🔐

Cryptography keeps your sensitive data on lockdown. There are a few different cryptography techniques to encrypt, or protect, data so you can share in confidence. Learn more about cryptography, encryption, and the methods used.

Cryptography is the method of protecting information with codes, and encryption is what you get from cryptography. Encryption is locking data so no one can see or access it except for authorized users with a key to decrypt it.

Cryptography concerns itself with four main objectives: confidentiality, integrity, non-repudiation and authentication. Cryptographic algorithms, or ciphers, encrypt and decrypt messages to secure communications among computer systems, devices like smartphones, and applications. Symmetric and asymmetric cryptography are the two main methods of encryption.

What cryptographic use cases have you encountered? How secure was the encryption method you used? Let us know in the comments and be sure to like this video.
