Visão Geral
An organization is the basic unit of Casdoor that manages users and applications. When a user signs in to an organization, they can access all applications belonging to that organization without needing to sign in again.
In the configuration of applications and providers, selecting an organization is important, as it determines whether users can access the application using specific providers.
You can also set up LDAP in Casdoor. Para mais detalhes, consulte a documentação LDAP.
O Casdoor fornece vários algoritmos de armazenamento de senha que podem ser selecionados na página de edição da organização.
| Nome | Algoritmo | Descrição | Cenário |
|---|---|---|---|
| plain | - | The password will be stored in cleartext (default). | - |
| salt | SHA-256 | SHA-256 é uma função de hash criptográfica patenteada que produz um valor de 256 bits de comprimento. | - |
| md5-salt | MD5 | A função de hash MD5 message-digest é uma função de hash quebrada criptograficamente, mas ainda amplamente utilizada, que produz um valor de hash de 128 bits. | Discuz! |
| bcrypt | bcrypt | bcrypt is a password-hashing function used to hash and salt passwords securely. | Spring Boot, WordPress |
| pbkdf2-salt | SHA-256 and PBKDF2 | PBKDF2 é uma função simples de derivação de chave criptográfica que é resistente a ataques de dicionário e ataques de tabela arco-íris. Foi originalmente implementado no Casdoor para o sincronizador Keycloak. Selecione esta opção se você estiver importando usuários usando o sincronizador Keycloak. | Keycloak |
Password Salt Configuration
For algorithms that use salts (salt, md5-salt, pbkdf2-salt), Casdoor provides flexible salt configuration. On the organization edit page, you can set the Password salt field to define how passwords are salted:
- Organization-level salt: When the
Password saltfield is set, all users in the organization share the same salt value. This ensures consistency across the organization. - Per-user random salt: When the
Password saltfield is left empty, Casdoor automatically generates a unique random salt for each user. This provides better security by preventing attackers from using precomputed hash tables across multiple users.
The per-user salt approach is recommended for new deployments as it provides stronger security against rainbow table attacks. Each user's salt is stored alongside their password hash and is automatically managed by Casdoor.
Use Email as Username
Organizations can enable the "Use email as username" option, which automatically uses the user's email address as their username during signup when the username field is not visible. This simplifies the registration process by eliminating the need for users to choose a separate username.
When this option is enabled:
- During signup, if the username field is hidden, the email address becomes the username automatically
- When users reset their email address, their username is updated to match the new email
- The system maintains consistency between the email and username fields
To enable this feature, check the "Use email as username" option on the organization edit page.
In addition to logging into Casdoor via an application (which redirects to Casdoor for SSO), Casdoor users can also choose to log in directly via the organization's login page: /login/<organization_name>, e.g., https://door.casdoor.com/login/casbin on the demo site.
