BLAKE2b Hash Generator for Fast, Secure Hashing Online
This BLAKE2b hash generator computes a cryptographic hash from your input. Choose a digest length from 1 to 64 bytes and optionally provide a key for keyed hashing, also known as a MAC. The tool uses the BLAKE2b variant, which has a 64-byte maximum digest and is designed for 64-bit platforms.
This BLAKE2b hash generator computes a cryptographic digest from content you enter in the browser. BLAKE2b is a high-speed cryptographic hash, and this tool uses the BLAKE2b variant with a maximum digest length of 64 bytes for 64-bit platforms. It can create a digest of 1 to 64 bytes, with an optional key for keyed hashing, also known as a MAC.
To use the tool, paste, drop, or enter your input, then adjust the available options and copy the resulting digest. The digest length controls how many bytes the output contains. Adding a key enables keyed hashing; leave it out for an unkeyed hash. BLAKE2b is the default in many modern tools, including b2sum, Argon2, and rclone.
A hash is a digest of input rather than an encrypted copy that can be decoded back into the original content. BLAKE2b can be useful when a workflow calls for a cryptographic hash or keyed MAC. Its configurable digest length lets you select an output size within the supported 1-to-64-byte range.
The tool runs entirely in your browser: input is processed on your device and is not uploaded, stored, or sent to a server. It is free and private, and after the page has loaded it works offline without a server dependency. This makes it useful for developers and DevOps engineers who want to hash content without installing a local utility or sending internal data to a third-party service.
Step 1: Paste, drop, or enter the content you want to hash. The tool processes that input as BLAKE2b data.
Step 2: Adjust the available options. Set a digest length from 1 to 64 bytes, and add an optional key if you need keyed hashing.
Step 3: Review the generated BLAKE2b hash. The result is a digest of your input, not an encrypted version of it.
Step 4: Copy the result for use in your workflow. Keep track of the chosen digest length and key if you need to reproduce a keyed hash.
Use case: Handle a routine BLAKE2b hashing task without installing anything locally. Generate the digest directly in your browser.
Use case: Hash content from a machine you are using temporarily. The browser-based tool can help when you cannot install a local utility.
Use case: Process internal data without sending it to a third-party service. The input is handled in your browser and is not sent to a server.
Use case: Create a keyed BLAKE2b hash when you need keyed hashing, also known as a MAC. Set an optional key along with the digest length.
Use case: Generate a digest for content used in a workflow involving tools such as b2sum, Argon2, or rclone. BLAKE2b is the default in these tools, according to the tool description.
Use case: Choose a shorter BLAKE2b digest when your use case calls for an output length below the 64-byte maximum. The available digest length ranges from 1 to 64 bytes.
