static String org.sleuthkit.datamodel.HashUtility.calculateMd5 ( AbstractFile file ) throws IOException

static

Calculate the MD5 hash for the given FsContent and store it in the database

Parameters

file	file object whose md5 hash we want to calculate

Returns: md5 of the given FsContent object

Exceptions

java.io.IOException

Deprecated:: Use calculateHashes() instead

static String org.sleuthkit.datamodel.HashUtility.calculateMd5Hash ( Content content ) throws IOException

static

Calculate the MD5 hash for the given FsContent

Parameters

content content object whose md5 hash we want to calculate

Returns: md5 of the given FsContent object

Exceptions

java.io.IOException

Deprecated:: Use calculateHashes() instead

static boolean org.sleuthkit.datamodel.HashUtility.isNoDataMd5 ( String md5 )

static

Determine if the passed in Hash value is that for no data (i.e. an empty file). Looking these values up or correlating on them causes lots of false positives.

Parameters

md5

Returns: True if it is the empty hash value

Definition at line 144 of file HashUtility.java.

static boolean org.sleuthkit.datamodel.HashUtility.isValidMd5Hash ( String md5Hash )

static

Determines whether a string representation of an MD5 hash is valid.

Parameters

md5Hash The hash.

Returns: True or false.

Definition at line 109 of file HashUtility.java.

static boolean org.sleuthkit.datamodel.HashUtility.isValidSha1Hash ( String sha1Hash )

static

Determines whether a string representation of a SHA-1 hash is valid.

Parameters

sha1Hash The hash.

Returns: True or false.

Definition at line 120 of file HashUtility.java.

static boolean org.sleuthkit.datamodel.HashUtility.isValidSha256Hash ( String sha256Hash )

static

Determines whether a string representation of a SHA-256 hash is valid.

Parameters

sha256Hash The hash.

Returns: True or false.
