  Bitcoin uses a cryptographic algorithm called SHA-256 (Secure Hash Algorithm 256-bit) to secure transactions. This algorithm takes the transaction data and creates a unique hash value, which is then used as the digital signature for the transaction. SHA-256 is a one-way function, meaning it is computationally infeasible to reverse the process and obtain the original data from the hash value. This ensures the integrity of the transaction and prevents tampering.

  The encryption used by Bitcoin is based on public-key cryptography. Each user has a pair of cryptographic keys: a public key and a private key. The public key is used to encrypt the transaction data, while the private key is used to decrypt it. Only the intended recipient, who possesses the corresponding private key, can decrypt and access the transaction details. This ensures the confidentiality of the transaction and prevents unauthorized access.

  Bitcoin employs a combination of encryption techniques to secure transactions. The use of SHA-256 ensures the integrity of the transaction data, while public-key cryptography provides confidentiality and authentication. These encryption methods work together to create a secure and decentralized system for conducting transactions.

  When it comes to encryption, Bitcoin doesn't mess around. It uses SHA-256, a powerful algorithm that generates a unique hash value for each transaction. This hash value acts as a digital fingerprint, ensuring that the transaction data remains intact and tamper-proof. So, rest assured, your Bitcoin transactions are protected by some serious encryption.
