Data to generate the hash for:	Max size of the input data is 10 MiB. ▲ clear By file upload: ▼ clear From URL (http[s], ftp[s]): ▼ clear By direct input: (UTF-8) Enter one or more wrappers (comma-separated): If necessary, enter initial data here: (UTF-8) Wrappers are executed in sequence on shared data string. For example, to supply base64-encoded stream of GZIP-compressed data enter wrappers: base64, gzip and fill the data input with the base64 stream. ¶ If data is not entered information from other tabs (upload, by URL and direct) is used to replace data on this page. This lets you enter gzip as a wrapper here and upload a file using upload tab while leaving data on this page empty. ¶ Currently supported wrappers are: base64, bzip, cslashes, datauri, direct, ftp, ftps, gzip, hex2bin, http, https, qprintable, upload, url, urlencoding, zlib. ¶ Upload By URL Direct input Custom Ctrl+Shift+E
In which format to output?	As string. Raw hash as space-separated hex bytes: 7E DC 00 4F Raw hash as hex bytes: 7EDC004F Raw hash as a C-style string: \xE1\xFA\x58\x0C Raw hash represented as HTML entities: áúX Raw (binary) hash.
Output hash letters in upper or lower case?	Upper
Summary view:	Textual (one line per item). Textual (comma-separated items on one line). JSON (JavaScript Object Notation). XML (eXtensible Markup Language). None (hide).

Hashing is a process of generating a string (or number) with limited width from a data stream of arbitrary length. Produced hash identifies that particular data stream while not exceeding a certain length. ¶

Of course, one hash matches many possible streams because it has limited width; however, good hash functions make it impossible to guess which data will have the same hash. Hashes can be reversible and irreversible; all hashes handled by this tool are irreversible meaning that you can't rebuild the original data stream given a hash string. ¶

Reference pages ¶

Reference pages on popular hashing algorithms: ¶

• MD5 (Message Digest 5) – very popular algorithm well-known for its entropy quality. Hash takes 16 bytes (128 bits) but is often converted to 32-character long string (simply a hexadecimal representation of raw hash) containing Latin characters (case-insensitive) and digits.
  • Short MD5 (sometimes MD5-24) – a case-sensitive version of MD5 hash function using extended alphabet (41 symbols). While still URL-safe it takes up to 24 characters instead of 32. PHP implementation are freely available here.
• SHA1 (Secure Hash Algorithm 1) – a 40-character long string which strength can be compared to that of MD5.
• CRC32 (Cyclic redundancy check) – basic, quick, widely used method of calculating checksums of data. The hash takes exactly 4 bytes (32 bits).
• Adler32 (Mark Adler's algorithm) – very similar to CRC32 but a bit faster and less reliable. Also takes up exactly 4 bytes (32 bits). Is a part of the very well-known ZLib compression library.

Less known hash functions that this tool uses: ¶

• HAVAL – produces hashes of different lengths (128, 160, 192, 224 and 256-bit hashes) and number of rounds (3, 4 or 5). Numbers in its name read as: HAVAL <bits>,<rounds>.
• Tiger – a hash initially designed for 64-bit platforms; used in DirectConnect (DC++) applications. Standard hash width is 192 bits.
• RIPEMD – cryptographic hash function designed in an open academic community. Standard hash width is 160 bits. Similar in performance to SHA-1.
