Encryption software is a type of program designed to protect sensitive information by converting it into a coded format that can only be read by authorized users. This process ensures that data remains confidential, even if it is intercepted by unauthorized parties. Common uses include securing personal communications, financial transactions, and sensitive corporate data. There are various types of encryption software available, ranging from full-disk encryption tools to file-level encryption applications. These tools utilize complex algorithms to encrypt data, making it nearly impossible for hackers to access without the correct decryption key. Popular examples include VeraCrypt and BitLocker.
