What is encryption software?

Encryption software transforms readable data (plaintext) into an unreadable format (ciphertext) to protect its confidentiality. It uses algorithms and keys to encrypt and decrypt data, ensuring that only authorized parties can access it. Encryption software is widely used to secure data at rest (e.g., on hard drives, databases) and in transit (e.g., during internet communication, email), protecting sensitive information from unauthorized access, theft, or tampering. Common use cases include securing financial transactions, protecting personal data, and ensuring secure communication.
