## What is a sha2 hash generator?

learn more about this tool
This tool generates random SHA2 message digests in your browser. The SHA2 hash function is actually the name for a family of four hash functions – SHA2-224, SHA2-256, SHA2-384, SHA2-512. These functions strengthen the original SHA-1 hash function that was released in 1995 by the NIST. The SHA2 hashes were published in 2001 by the NSA and they are built from a one-way compression function, by using the collision-resistant Merkle–Damgard construction and the Davies–Meyer single-block-length compression structure. The number at the end of SHA prefix indicates the size of the hash digest. For SHA224 it's 224 bits (28 bytes), for SHA256 it's 256 bits (32 bytes), for SHA384 it's 384 bits (48 bytes), and for SHA512 it's 512 bits (64 bytes). Instead of printing that many bits, the hash is usually printed as a hexadecimal string. For example, SHA2-224 is printed as 56 hexadecimal digits. If you need to generate checksums that match a certain pattern (such as require that SHA2 begins with ten zeros), then you can enter a glob-like pattern in the options. If you need SHA2 in some other base than hexadecimal, then we also support custom SHA2 bases, such as binary, octal, and decimal. If that's not enough, you can also choose the custom-base option and enter any base you like up to base 36. Hashabulous!

## Sha2 hash generator examples

Click to useSeven Random SHA2 Hashes

This example generates seven random SHA2 (original SHA-224) cryptographic hashes. Each digest is 224 bits in size and when represented in hex encoding, it's 56 characters long.

SHA2-256 That Start with Zeros

In this example, we require that the generated SHA-256 digest messages match a glob pattern that that starts with eight zeros and ends with a nine. As SHA-256 is 256 bits long, then the size of each hash is 64 hexadecimal digits.

Base-32 SHA2-384 Hashes

In this example, we calculate four random SHA-384 hash codes in base-32. The number 384 indicates that these hashes are 384 bits long (or 96 nibbles long, or 48 bytes long, or 24 words long). To represent 384 bits in base-32, we need 384/log2(32) symbols, which is 76.8. As we can't print partial symbols, we round it up to 77 and get that each SHA-384 code has the length of 77 characters in base-32. Also for a change, we convert all base-32 symbols to upper case.

This example calculates three random SHA-512 hash values. SHA512 is as high as SHA2 algorithm can go with 512 bits in the output hash value. When printed in decimal form, each hash takes 155 digits.
