Class StandardPasswordEncoder

java.lang.Object
org.springframework.security.crypto.password.StandardPasswordEncoder
All Implemented Interfaces:
PasswordEncoder
@Deprecated public final class StandardPasswordEncoder extends Object implements PasswordEncoder
Deprecated.
Digest based password encoding is not considered secure. Instead use an adaptive one way function like BCryptPasswordEncoder, Pbkdf2PasswordEncoder, or SCryptPasswordEncoder. Even better use DelegatingPasswordEncoder which supports password upgrades. There are no plans to remove this support. It is deprecated to indicate that this is a legacy implementation and using it is considered insecure.
This PasswordEncoder is provided for legacy purposes only and is not considered secure. A standard PasswordEncoder implementation that uses SHA-256 hashing with 1024 iterations and a random 8-byte random salt value. It uses an additional system-wide secret value to provide additional protection.

The digest algorithm is invoked on the concatenated bytes of the salt, secret and password.

If you are developing a new system, BCryptPasswordEncoder is a better choice both in terms of security and interoperability with other languages.

  • Constructor Details

    • StandardPasswordEncoder

      public StandardPasswordEncoder()
      Deprecated.
      Constructs a standard password encoder with no additional secret value.

    • StandardPasswordEncoder

      public StandardPasswordEncoder(CharSequence secret)
      Deprecated.
      Constructs a standard password encoder with a secret value which is also included in the password hash.
      Parameters:
      secret - the secret key used in the encoding process (should not be shared)

  • Method Details

    • encode

      public String encode(CharSequence rawPassword)
      Deprecated.
      Description copied from interface: PasswordEncoder
      Encode the raw password. Generally, a good encoding algorithm applies a SHA-1 or greater hash combined with an 8-byte or greater randomly generated salt.
      Specified by:
      encode in interface PasswordEncoder

    • matches

      public boolean matches(CharSequence rawPassword, String encodedPassword)
      Deprecated.
      Description copied from interface: PasswordEncoder
      Verify the encoded password obtained from storage matches the submitted raw password after it too is encoded. Returns true if the passwords match, false if they do not. The stored password itself is never decoded.
      Specified by:
      matches in interface PasswordEncoder
      Parameters:
      rawPassword - the raw password to encode and match
      encodedPassword - the encoded password from storage to compare with
      Returns:
      true if the raw password, after encoding, matches the encoded password from storage
