Method Detail

values

public static PBES2Algorithm[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (PBES2Algorithm c : PBES2Algorithm.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static PBES2Algorithm valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

fromOid

public static PBES2Algorithm fromOid(String oid)

Gets the PBE algorithm for the given object identifier.

Parameters:

oid - PBE algorithm OID.

Returns:

Algorithm whose identifier equals given value.

Throws:

IllegalArgumentException - If no matching algorithm found.

getOid

public String getOid()

Returns:

the oid

getSpec

public AlgorithmSpec getSpec()

Returns:

Cipher algorithm specification.

getKeySize

public int getKeySize()

Returns:

Size of derived key in bits or -1 if algorithm does not define a key size.
