Decode / decrypt / lookup a SHA1 hash

This tool searches multiple SHA1 rainbow tables for matches to a large number of SHA1 hashes. SHA1 is a hashing algorithm and therefore is technically not encryption, but hashes can be resolved using lookup rainbow tables. The database contains millions of SHA1 hashes and matching sources. Hashes are generated from a number of lookup sources, procedural generation using multiple UTF-8 charsets and also includes sets of raw binary data.

To perform lookups on alternative hashes there are sites for MD5, SHA1, SHA256, SHA512 and CRC32

About SHA1 hashes

"SHA-1 forms part of several widely used security applications and protocols, including TLS and SSL, PGP, SSH, S/MIME, and IPsec. Those applications can also use MD5; both MD5 and SHA-1 are descended from MD4. Revision control systems such as Git, Mercurial, and Monotone use SHA-1 not for security but to identify revisions and to ensure that the data has not changed due to accidental modification.
