1、在函数encrypt_password上打断点,然后客户端执行:create user yzs with password ‘123456’;创建带密码的用户,观察是否默认使用md5。 postgres=# create user yzs with password '123456'; 1. 2、堆栈信息 Breakpoint 1, encrypt_password (target_type=PASSWORD_TYPE_MD5, role=0x99c3b3c "yzs", password=...
PG用户通过md5加密时，加了salt，而这个salt是用户名字符串。二、源码分析CreateRole： shadow_pass = encrypt_password(Password_encryption, stmt->role,password); |-- pg_md5_encrypt(password, role, strlen(role),encrypted_password); | |-- memcpy(crypt_buf, passwd, passwd_len); | | m...
那就只有salt的熵了(期望用户密码拥有足够的熵不靠谱). 而提升salt的长度可以有效提升存储熵的空间. 这...

The MD5 authentication method double-encrypts the password on the client before sending it to the server. It first MD5-encrypts it based on the user name, and then encrypts it based on a random salt sent by the server when the database connection was made. It is this double-encrypted ...
