Cryptography

Cryptography is the practice of securing information using mathematical algorithms and protocols, ensuring the confidentiality, integrity, and authenticity of data. In the world of cryptocurrencies, cryptography is foundational to securing transactions, protecting user wallets, and safeguarding blockchain networks against fraud or unauthorized access. Common cryptographic techniques used in crypto include hashing, public-key cryptography, and digital signatures.

Public-key cryptography is used to create pairs of keys: a public key that can be shared openly and a private key that is kept secret. These keys allow users to send and receive cryptocurrencies securely by encrypting and decrypting transactions. Digital signatures provide additional security by verifying the authenticity of a transaction, ensuring that it was initiated by the rightful owner of the private key. Together, these cryptographic methods ensure the security and transparency of blockchain networks.
