Results and SHA1 Format
How many SHA1 hashes to generate?
Custom format for generating SHA1s.
For example, if the format is "abc*000*", then it will generate SHA1 checksums that start with "abc" and have three zeros somewhere. The pattern only works in hexadecimal output base.
SHA1 Base
If you selected custom SHA1 base, then enter it here. (Bases allowed: 2 - 36.)
SHA1 Output Options
Place this symbol between SHA1 hashes.
Sha1 hash generator tool What is a sha1 hash generator?
This tool generates random SHA1 hash values in your browser. The SHA1 digest is one of several cryptographic hash functions. It's often used to verify that a file has been unaltered. It was developed by the NSA (US National Security Agency) and published by the NIST (National Institute of Standards and Technology). It's 160 bits in size or 40 hex symbols in length (one hex symbol is 4 bits). This utility also lets you enter the number of SHA1 checksums to generate, set a pattern for SHA1 checksums (such as require all checksums to begin with five zeros) and change the output radix (base) to bin, oct, dec, or custom. Additionally, if you require an upper case or lower case output, we have options for that as well. Hashabulous!
Sha1 hash generator examples Click to use
Six Random SHA1 Hashes
This example calculates six random SHA-1 cryptographic hashes and converts them to uppercase. Each checksum is 40 digits long and is encoded as a hexadecimal number.

SHA1 That Matches a Wildcard
In this example, we generate SHA1s that match the given wildcard format. The wildcard is "00000*fffff*00000", which means generate hashes that start and end with five zeros and have five f's in between.

Octal SHA1s
In this example, we create valid SHA1 digests and convert them to the octal radix. To do it, we first generate them as hex numbers and then convert them to the octal number base. To represent 160 bits in the octal base, we need 53.3 characters, so we round it up to 54 octal characters.
