Tools to decode / decrypt / reverse lookup SHA1 hashes

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 and reversed using lookup rainbow tables. The database contains millions of SHA1 hashes and matching sources. Hashes have been generated from a large number of sources, including procedural generation using multiple UTF-8 charsets, common dictionary lists and also sets of raw binary data. Most hashes are also stored with their double hash or treble hash, along with binary versions.

To perform reverse lookups on alternative hashes there are sites for MD2, MD4 and MD5, along with SHA1, SHA256, SHA512 and CRC32

Hash generators are available for MD2, MD4, 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.

Other decoders: MD5 | SHA1 | SHA256 | SHA512 | CRC32
