Constructs a parameter set for password-based encryption as defined in the PKCS #5 standard.

Public methods

int getIterationCount()

Returns the iteration count.

AlgorithmParameterSpec getParameterSpec()

Returns the cipher algorithm parameter specification.

byte[] getSalt()

Returns the salt.

Public constructors

PBEParameterSpec

added in API level 1
public PBEParameterSpec (byte[] salt, 
                int iterationCount)

Constructs a parameter set for password-based encryption as defined in the PKCS #5 standard.

Parameters
salt byte: the salt. The contents of salt are copied to protect against subsequent modification.

iterationCount int: the iteration count.

Throws
NullPointerException if salt is null.

PBEParameterSpec

added in API level 26
public PBEParameterSpec (byte[] salt, 
                int iterationCount, 
                AlgorithmParameterSpec paramSpec)

Constructs a parameter set for password-based encryption as defined in the PKCS #5 standard.

Parameters
salt byte: the salt. The contents of salt are copied to protect against subsequent modification.

iterationCount int: the iteration count.

paramSpec AlgorithmParameterSpec: the cipher algorithm parameter specification, which may be null.

Throws
NullPointerException if salt is null.

Public methods

getIterationCount

added in API level 1
public int getIterationCount ()

Returns the iteration count.

Returns
int the iteration count

getParameterSpec

added in API level 26
public AlgorithmParameterSpec getParameterSpec ()

Returns the cipher algorithm parameter specification.

Returns
AlgorithmParameterSpec the parameter specification, or null if none was set.

getSalt

added in API level 1
public byte[] getSalt ()

Returns the salt.

Returns
byte[] the salt. Returns a new array each time this method is called.
