AesKeyStrength

private AesKeyStrength(int rawCode,
                       int saltLength,
                       int macLength,
                       int keyLength)

Method Detail

values

public static AesKeyStrength[] 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 (AesKeyStrength c : AesKeyStrength.values())
    System.out.println(c);

Returns:

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

valueOf

public static AesKeyStrength valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

getRawCode

public int getRawCode()

Get the code written to the ZIP file

Returns:

the code written the ZIP file

getSaltLength

public int getSaltLength()

getMacLength

public int getMacLength()

getKeyLength

public int getKeyLength()

Get the key length in bytes that this AesKeyStrength represents

Returns:

the key length in bytes

getAesKeyStrengthFromRawCode

public static AesKeyStrength getAesKeyStrengthFromRawCode(int code)

Get a AesKeyStrength given a code from the ZIP file

Parameters:

code - the code from the ZIP file

Returns:

the AesKeyStrength that represents the given code, or null if the code does not match
