Method Details

encode

public String encode(CharSequence rawPassword)

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

Parameters:

rawPassword - the raw password to encode

encode

public String encode(CharSequence rawPassword,
 byte[] salt)

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

Parameters:

rawPassword - the raw password to encode

salt - the salt use to encode the rawPassword

matches

public boolean matches(CharSequence rawPassword,
 String encodedPassword)

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

matches

public boolean matches(CharSequence rawPassword,
 String encodedPassword,
 byte[] salt)

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

salt - the salt use to compare the rawPassword and the encodedPassword

Returns:

matches

public boolean matches(CharSequence rawPassword,
 String encodedPassword,
 String salt)

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

salt - the salt use to compare the rawPassword and the encodedPassword

Returns:

setAlgorithm

setSaltLength

public void setSaltLength(int saltLength)

setPasswordSaltFormat

public void setPasswordSaltFormat(String passwordSaltFormat)
