About

• Cryptography is the name for techniques that secure information by converting plain text into ciphertext (encrypted data that is unreadable until it is decrypted).
• Cryptography is most often associated with scrambling plaintext (ordinary text) into ciphertext (a process called encryption), then back again (known as decryption).
• Only the sender and the receiver can understand the encrypted message and a malicious actor who interferes with the communication can’t understand it.

• Cryptography is an essential cybersecurity tool. It ensures confidentiality, authentication and integrity of data.
