What are the methods of password encryption?
Article Introduction:Password encryption methods include: 1. Use symmetric encryption algorithms (such as 3DES, AES) to encrypt. Using this method of encryption can restore the original password through decryption. Of course, the prerequisite is to obtain the key; 2. Use One-way HASH algorithm (such as MD5, SHA1) is used for password, but the original password cannot be restored through calculation; 3. Use a special one-way HASH algorithm for password; 4. Use PBKDF2 algorithm for encryption; 5. Use BCrypt algorithm for encryption; 6. Use SCrypt algorithm for encryption.

Password encryption mechanism in PHP projects
Article Introduction:In PHP projects, password security is crucial. Because password theft may cause substantial losses to users and affect the normal operation of the system. In order to protect the security of passwords, we can use password encryption mechanisms. The password encryption mechanism can convert plain text passwords into cipher text passwords, thereby improving password security. Even if a hacker steals the password, he cannot easily obtain the clear text password. At the same time, the password encryption mechanism can also prevent malicious attacks and internal data leakage. In PHP projects, the password encryption mechanism can be implemented through

What encryption method is mysql password?
Article Introduction:MySQL password is SHA-1 encryption method. It is an encryption method based on a hash algorithm, which converts the entered password into a hash value of 40 characters in length. The hash value is unique and irreversible. In MySQL, when user passwords are stored, what is actually stored is a hash value rather than a clear text password. Even if the database is attacked and the password file is leaked, the hacker will not be able to know the user's real password because it cannot be reversed from the hash value. Push out the original password.

Symmetric encryption cryptography in Java
Article Introduction:IntroductionSymmetric encryption, also known as key encryption, is an encryption method in which the same key is used for encryption and decryption. This encryption method is fast and efficient and suitable for encrypting large amounts of data. The most commonly used symmetric encryption algorithm is Advanced Encryption Standard (AES). Java provides strong support for symmetric encryption, including classes in the javax.crypto package, such as SecretKey, Cipher, and KeyGenerator. Symmetric encryption in Java The JavaCipher class in the javax.crypto package provides cryptographic functions for encryption and decryption. It forms the core of the Java Cryptozoology Extensions (JCE) framework. In Java, the Cipher class provides symmetric encryption functions, and K

Asymmetric encryption cryptography in Java
Article Introduction:Cryptography is the study and practice of different techniques to protect communications from interference by third parties. It is used for network security. We attempt to develop methods and practices to protect sensitive data. The only goal of cryptography is to protect data from attackers. Asymmetric encryption is also known as public/private key encryption. The private key, as the name suggests, will remain private, while the public key can be distributed. Encryption is a mathematical relationship between two keys, one for encryption and the other for decryption. For example, if there are two keys "A1" and "A2", then if key "A1" is used for encryption, "A2" is used for decryption and vice versa. We use the RSA algorithm for asymmetric encryption. First we generate a pair of keys (public key, private key). Cryptozoology Togen of Asymmetric Encryption in Java

What are cryptosystems with different encryption and decryption keys called?
Article Introduction:Cryptosystems with different encryption and decryption keys are called public key encryption systems; public key encryption is also called asymmetric encryption, in which public key encryption is asymmetric. Compared with symmetric conventional encryption that uses only one key, It involves the use of two independent keys, one key is called the private key, which is kept secret, and the other key is called the public key and does not need to be kept secret.
