Constants
TYPE_PARTIAL_MERKLE_ROOT_1M_SHA256
static val TYPE_PARTIAL_MERKLE_ROOT_1M_SHA256: Int
Root SHA256 hash of a 1M Merkle tree computed over protected content. Excludes signing block. See APK Signature Scheme V2.
Value: 32
TYPE_PARTIAL_MERKLE_ROOT_1M_SHA512
static val TYPE_PARTIAL_MERKLE_ROOT_1M_SHA512: Int
Root SHA512 hash of a 1M Merkle tree computed over protected content. Excludes signing block. See APK Signature Scheme V2.
Value: 64
TYPE_WHOLE_MD5
static valTYPE_WHOLE_MD5: Int
Deprecated: Not platform enforced. Cryptographically broken and unsuitable for further use. Use platform enforced digests e.g. TYPE_WHOLE_MERKLE_ROOT_4K_SHA256
. Provided for completeness' sake and to support legacy usecases.
MD5 hash computed over all file bytes.
Value: 2
TYPE_WHOLE_MERKLE_ROOT_4K_SHA256
static val TYPE_WHOLE_MERKLE_ROOT_4K_SHA256: Int
Root SHA256 hash of a 4K Merkle tree computed over all file bytes. See APK Signature Scheme V4. See fs-verity. Recommended for all new applications. Can be used by kernel to enforce authenticity and integrity of the APK. See fs-verity for details
Value: 1
TYPE_WHOLE_SHA1
static valTYPE_WHOLE_SHA1: Int
Deprecated: Not platform enforced. Broken and should not be used. Use platform enforced digests e.g. TYPE_WHOLE_MERKLE_ROOT_4K_SHA256
. Provided for completeness' sake and to support legacy usecases.
SHA1 hash computed over all file bytes.
Value: 4
TYPE_WHOLE_SHA256
static valTYPE_WHOLE_SHA256: Int
Deprecated: Not platform enforced. Use platform enforced digests e.g. TYPE_WHOLE_MERKLE_ROOT_4K_SHA256
. Provided for completeness' sake and to support legacy usecases.
SHA256 hash computed over all file bytes.
Value: 8
TYPE_WHOLE_SHA512
static valTYPE_WHOLE_SHA512: Int
Deprecated: Not platform enforced. Use platform enforced digests e.g. TYPE_WHOLE_MERKLE_ROOT_4K_SHA256
. Provided for completeness' sake and to support legacy usecases.
SHA512 hash computed over all file bytes.
Value: 16
