SHA256 Format and Results
Number of SHA256 digests to output.
Hex glob for the generator.
For example, a glob "1a2*ff" will generate hashes that start with "1a2" and end with "ff". Glob patterns work only with hexadecimal digits.
SHA256 Output Radix
Specify your own radix for SHA-256. Valid radixes are 2 - 36.
Customize SHA256 Output
Put this character after every checksum.
Output SHA256 in lower-case letters.
Output SHA256 in upper-case letters.
Output SHA256 in random-case letters.
Sha-256 hash generator tool What is a sha-256 hash generator?
This tool generates random Secure Hash Algorithm (SHA-256) checksums in your browser. SHA256 is one of the second generation SHA hash algorithms that are built using collision-resistant cryptographic compression functions. The initial values for SHA256 are generated using the method described in FIPS Publication 180-4. This hash function is optimized for use on x86 32-bit architecture as it uses 4-byte words. The value "256" in SHA256 is the message digest size in bits, which is 32 bytes. With this utility, you can generate as many SHA256 hashes you need in any format, base, and case. The format can be specified using glob pattern matching syntax. For example, a glob "*00ff*ff00" will generate hashes that contain "00ff" and end with "ff00". Supported bases are all bases from 2 to 36. Supported cases are lowercase, uppercase and randomcase. Hashabulous!

Four Random SHA256 Hashes
This example calculates four random SHA256 message digests. Each digest is 256 bits in length but when printed as hexadecimal, it's only 64 characters in length.

SHA256 Glob Pattern
In this example, we use a glob pattern to generate six SHA-256 hashes. The glob pattern is "*c0de*c0ffee*" that constructs a hash with the patterns "c0de" and "c0ffee" somewhere in the hash (can be at the start, middle or end).

SHA256 in Base2
In this example, we change the output base to binary and set count to 3. That creates two SHA256 values that consist of 256 zeros and ones.
