What is Encryptions?

Encryption is the process of converting readable data (plaintext) into an unreadable format (ciphertext) to protect its confidentiality. It's commonly used to secure data at rest (e.g., on hard drives or in databases) and data in transit (e.g., over the internet). Encryption algorithms use keys to encrypt and decrypt the data, and the strength of the encryption depends on the algorithm and the key size.
