Enum Constant Summary

Enum Constants

Enum Constant	Description
DES	Deprecated. This is the old-school weakest form, do not use unless somehow absolutely required.
MD5	Deprecated. As of glibc 2.7, prefer the stronger SHA256 and SHA512 alternatives.
SHA256	SHA-256 algorithm requires glibc 2.7+.
SHA512	SHA-512 algorithm requires glibc 2.7+.

Method Summary

Modifier and Type	Method	Description
String	generateSalt(SecureRandom secureRandom)	Generates a random salt for this algorithm.
int	getSaltLength()	Gets the number of characters in the salt, not including the prefix.
String	getSaltPrefix()
static PosixFile.CryptAlgorithm	valueOf(String name)	Returns the enum constant of this type with the specified name.
static PosixFile.CryptAlgorithm[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

DES

@Deprecated
public static final PosixFile.CryptAlgorithm DES

Deprecated.

This is the old-school weakest form, do not use unless somehow absolutely required.

DES algorithm.

MD5

@Deprecated
public static final PosixFile.CryptAlgorithm MD5

Deprecated.

As of glibc 2.7, prefer the stronger SHA256 and SHA512 alternatives.

MD5 algorithm.

SHA256

public static final PosixFile.CryptAlgorithm SHA256

SHA-256 algorithm requires glibc 2.7+.

SHA512

public static final PosixFile.CryptAlgorithm SHA512

SHA-512 algorithm requires glibc 2.7+.

Method Detail

values

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

Returns:

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

valueOf

public static PosixFile.CryptAlgorithm 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

getSaltPrefix

public String getSaltPrefix()

getSaltLength

public int getSaltLength()

Gets the number of characters in the salt, not including the prefix.

generateSalt

public String generateSalt(SecureRandom secureRandom)

Generates a random salt for this algorithm.
