Data encryption software: protecting your data
本帖最後由 hmdahsan113 於 2024-9-23 11:58 編輯security Data encryption software is an important tool for protecting data security. It achieves this by converting data into ciphertext that can only be interpreted by authorized personnel. With the frequent occurrence of data leaks, the importance of data encryption has become increasingly prominent. Classification of data encryption software Depending on the encryption method, data encryption software is mainly divided into the following categories.
Symmetric encryption: Use the same key for Email List encryption and decryption. Advantages: Fast encryption and decryption speed. Disadvantages: Complex key management. Once the key is leaked, data security cannot be guaranteed. Common algorithms: AES, DES, etc. Asymmetric encryption: Use a pair of keys, the public key is used for encryption, and the private key is used for decryption. Advantages: Key management is relatively safe and suitable for large-scale data transmission.

Disadvantages: Slow encryption and decryption speed. Common algorithms: RSA, ECC, etc. Hash algorithm: Convert data of any length into a hash value of fixed length. Features: Irreversible, that is, the original data cannot be restored from the hash value . Application: Password storage, data integrity verification, etc. Common algorithms: SHA-256, MD5, etc. Functions of data encryption software File encryption: Encrypt a single file or an entire folder. Disk encryption: Encrypt the entire disk to protect all data stored on the disk.
