Class PlaintextPasswordEncoder

java.lang.Object

org.springframework.security.authentication.encoding.BasePasswordEncoder

org.springframework.security.authentication.encoding.PlaintextPasswordEncoder

All Implemented Interfaces:

PasswordEncoder

Deprecated.

This class will be removed in Spring Security 5. For passivity switch to NoOpPasswordEncoder.

@Deprecated
public class PlaintextPasswordEncoder
extends BasePasswordEncoder

Plaintext implementation of PasswordEncoder.

As callers may wish to extract the password and salts separately from the encoded password, the salt must not contain reserved characters (specifically '{' and '}').

Method Detail

encodePassword

public String encodePassword(String rawPass,
                             Object salt)

Deprecated.

Description copied from interface: PasswordEncoder

Encodes the specified raw password with an implementation specific algorithm.

This will generally be a one-way message digest such as MD5 or SHA, but may also be a plaintext variant which does no encoding at all, but rather returns the same password it was fed. The latter is useful to plug in when the original password must be stored as-is.

The specified salt will potentially be used by the implementation to "salt" the initial value before encoding. A salt is usually a user-specific value which is added to the password before the digest is computed. This means that computation of digests for common dictionary words will be different than those in the backend store, because the dictionary word digests will not reflect the addition of the salt. If a per-user salt is used (rather than a system-wide salt), it also means users with the same password will have different digest encoded passwords in the backend store.

If a salt value is provided, the same salt value must be use when calling the PasswordEncoder.isPasswordValid(String, String, Object) method. Note that a specific implementation may choose to ignore the salt value (via null), or provide its own.

Parameters:

rawPass - the password to encode

salt - optionally used by the implementation to "salt" the raw password before encoding. A null value is legal.

Returns:

encoded password

isIgnorePasswordCase

public boolean isIgnorePasswordCase()

Deprecated.

isPasswordValid

public boolean isPasswordValid(String encPass,
                               String rawPass,
                               Object salt)

Deprecated.

Description copied from interface: PasswordEncoder

Validates a specified "raw" password against an encoded password.

The encoded password should have previously been generated by PasswordEncoder.encodePassword(String, Object). This method will encode the rawPass (using the optional salt), and then compared it with the presented encPass.

For a discussion of salts, please refer to PasswordEncoder.encodePassword(String, Object).

Parameters:

encPass - a pre-encoded password

rawPass - a raw password to encode and compare against the pre-encoded password

salt - optionally used by the implementation to "salt" the raw password before encoding. A null value is legal.

Returns:

true if the password is valid , false otherwise

obtainPasswordAndSalt

public String[] obtainPasswordAndSalt(String password)

Deprecated.

Demerges the previously encodePassword(String, Object)String.

The resulting array is guaranteed to always contain two elements. The first is the password, and the second is the salt.

Throws an exception if null or an empty String is passed to the method.

Parameters:

password - from encodePassword(String, Object)

Returns:

an array containing the password and salt

setIgnorePasswordCase

public void setIgnorePasswordCase(boolean ignorePasswordCase)

Deprecated.

Indicates whether the password comparison is case sensitive.

Defaults to false, meaning an exact case match is required.

Parameters:

ignorePasswordCase - set to true for less stringent comparison
