Enum Constant Detail

SHA1

public static final DigestAlgorithm SHA1

SHA-1 digest.

Android 2.3 (API Level 9) to 4.2 (API Level 17) (inclusive) do not support SHA-2 JAR signatures.

Moreover, platforms prior to API Level 18, without the additional Digest-Algorithms attribute, only support SHA or SHA1 algorithm names in .SF and MANIFEST.MF attributes.

SHA256

public static final DigestAlgorithm SHA256

SHA-256 digest.

Field Detail

API_SHA_256_RSA_AND_ECDSA

public static final int API_SHA_256_RSA_AND_ECDSA

API level which supports SHA256 with SignatureAlgorithm.RSA and SignatureAlgorithm.ECDSA.

See Also:

Constant Field Values

API_SHA_256_ALL_ALGORITHMS

public static final int API_SHA_256_ALL_ALGORITHMS

API level which supports SHA256 for all SignatureAlgorithms.

Before that, SHA256 can only be used with RSA and ECDSA.

Constant Field Values

messageDigestName

@Nonnull
public final java.lang.String messageDigestName

Name of algorithm for message digest.

manifestAttributeName

@Nonnull
public final java.lang.String manifestAttributeName

Name of attribute in signature file with the manifest digest.

entryAttributeName

@Nonnull
public final java.lang.String entryAttributeName

Name of attribute in entry (both manifest and signature file) with the entry's digest.

Method Detail

values

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

Returns:

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

valueOf

public static DigestAlgorithm 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
