Today, we are going to discuss what is cryptography in simple words and how does it work? hope this might help you.
Cryptography is the study and practice of sending secure, encrypted messages between two or more parties. Cryptography allows digital currency transactions to be pseudonymous, secure, and “trustless” – with no bank or other intermediary required.
The “crypto” in the word “cryptocurrency” means “secret” in Greek – which gives you a clue as to what the field of cryptography is all about. Cryptography is the study and practice of sending secure, encrypted messages or data between two or more parties. The sender “encrypts” the message, which obscures its content to a third party, and the receiver “decrypts” the message, making it legible again.
How does Cryptography work?
The functioning of cryptography revolves around cryptographic algorithms. Cryptographic algorithms or ciphers are mathematical functions that are combined with keys, such as phrase, digit, word, etc., to encrypt text. The effectiveness depends on the strength of the cryptographic algorithms and the secrecy level of the key.
Multiple complex combinations of algorithms and keys boost the effectiveness of a cryptosystem.
