ByteExtensions¶

Byte-array helpers for locating a known signature (e.g. a PDF header), stripping a leading header, and hashing a payload. (BR-053, BR-054, BR-056)

Purpose¶

Byte-array helpers for locating a known signature (e.g. a PDF header), stripping a leading header, and hashing a payload. (BR-053, BR-054, BR-056)

Member	Signature	Purpose
PDF_FILE_HEADER	`public const string PDF_FILE_HEADER = "%PDF-"`	Well-known signature identifying a PDF file's leading bytes.
Search(this byte[] source, string signature, int startIndex, int endIndex)	`public static int Search(this byte[] source, string signature, int startIndex, int endIndex)`	Finds the index of a string signature within a byte range, or -1 if not found. (BR-053, BR-054)
Search(this byte[] source, byte[] signature, int startIndex, int endIndex)	`public static int Search(this byte[] source, byte[] signature, int startIndex, int endIndex)`	Finds the index of a byte signature within a byte range, or -1 if not found. (BR-054)
StripHeader(this byte[] source, string signature, out bool found, int maxSearchLength)	`public static byte[] StripHeader(this byte[] source, string signature, out bool found, int maxSearchLength)`	Removes bytes preceding a located signature, reporting whether the signature was found. (BR-055, BR-056)
GetMD5Hash(this byte[] source)	`public static string GetMD5Hash(this byte[] source)`	Computes the MD5 hash of the byte array and renders it as a hex string. (BR-057)
