About HAS-160 Hash Generator
HAS-160 is a cryptographic hash function designed for use with the Korean KCDSA digital signature algorithm. It is derived from SHA-1, with assorted changes intended to increase its security. It produces a 160-bit output. HAS-160 is used in the same way as SHA-1. First it divides input in blocks of 512 bits each and pads the final block. A digest function updates the intermediate hash value by processing the input blocks in turn. The message digest algorithm consists, by default, of 80 rounds.
Input: binary bytes (text input uses UTF-8; a file retains its original bytes). Output: text.

Before interpreting the result
Use a checksum to compare exact bytes against a trusted digest. Choose a password hashing function for passwords and a MAC for keyed authentication. MD5 and SHA-1 are unsuitable for new security-sensitive designs.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
