The BLAKE encryption tool is a powerful online hash function calculator that focuses on the BLAKE series of algorithms. It supports the widely used BLAKE2B and BLAKE2S hash algorithms, which can be used for data integrity verification, message authentication code (MAC) generation, digital signatures, and other scenarios. Users can flexibly configure the string to be hashed, hash algorithm, input data type, key, output bits, case, salt (and its position), encryption rounds, and character encoding to meet different security and performance needs.
Introduction to BLAKE Hash Algorithm
The BLAKE hash function is one of the final round candidate algorithms in the NIST SHA-3 competition, and is known for its excellent performance and security. It draws on the advantages of SHA-2 and ChaCha in design, provides excellent hashing speed, and even exceeds MD5 and SHA-1 on some platforms, while maintaining the same or higher security level as SHA-3.
BLAKE2B: Optimized for 64-bit platforms, providing hash output up to 512 bits, suitable for high-performance servers and large datasets.
BLAKE2S: Optimized for 8-bit to 32-bit platforms, providing hash output up to 256 bits, suitable for embedded devices and resource-constrained environments.
The BLAKE series of algorithms natively supports keys (for MAC functions) and salts, which makes it more convenient and secure to build authentication and anti-tampering mechanisms.
How to Use
Enter the string to be encrypted: Enter the data you need to hash in the "String to be encrypted" text box.
Select algorithm: Select the hash algorithm you want to use from the drop-down menu, BLAKE2B or BLAKE2S.
Select input type: According to the format of the data you enter, select "Plaintext", "Hex", "Base64" or "Bytes".
Enter key: Enter the key used for MAC calculation in the "Key" field. If the MAC function is not required, you can enter an empty string or any default value, but this field is required.
Set output bits: Enter the length of the hash result you expect in the "Output Bits" field (for example, 32, 64, 128, etc.). BLAKE2B supports up to 512 bits, and BLAKE2S supports up to 256 bits.
Select case: Select the display case of the hash result (Hex format), "Lowercase" or "Uppercase".
Enter salt (optional): If you need to increase the randomness of the hash, you can enter the salt value in the "Salt" field. This field can be left blank.
Select salt position (optional): If you fill in the salt value, select whether the salt value is combined with the content to be processed as a prefix (start) or a suffix (end).
Set the number of encryption rounds (optional): Enter the number of repeated hashes in the "Encryption Rounds" field, the default is 1. This function is mainly used to increase the calculation time and increase the difficulty of brute force cracking.
Select character encoding: Select the character encoding of the input string, supporting UTF-8, ASCII and ISO-8859-1.
Click the execute button, and the tool will calculate and display the hash result according to your configuration.
Output result format description: The calculation result will be displayed in list form, including hash values in Hex, Base64 and Bytes formats.
Usage Example
The following is an example of using the BLAKE2B algorithm with a key and custom output bits:
String to be encrypted: Hello BLAKE hash!
Algorithm: BLAKE2B
Input Type: Plaintext
Key: mysecretkey
Output Bits: 32
Case: Lowercase
Salt: (Leave blank)
Encryption Rounds: 1
Character Encoding: UTF-8
Operation Demonstration:
Enter "Hello BLAKE hash!" in "String to be encrypted".
Select "BLAKE2B" for "Algorithm".
Select "Plaintext" for "Input Type".
Enter "mysecretkey" for "Key".
Enter "32" for "Output Bits".
Select "Lowercase" for "Case".
Keep "Salt" empty.
Keep "Encryption Rounds" as "1".
Select "UTF-8" for "Character Encoding".
Click the "Calculate" button.
Expected Output Result:

Common Questions
Q: What is the difference between BLAKE hash and MD5, SHA-256? A: The BLAKE series of hash functions are designed to provide higher performance and security. Compared to MD5 (which has been proven to be insecure) and SHA-256, BLAKE2 maintains the security level of SHA-3, and its hashing speed is comparable to MD5/SHA-1, or even faster, especially on multi-core processors. BLAKE natively supports keys (MAC function) and salts, making it more flexible and secure when building message authentication and anti-tampering mechanisms.
Q: What are the limitations of the output bits? A: The BLAKE2B algorithm supports a maximum of 512 bits of hash output, and the BLAKE2S algorithm supports a maximum of 256 bits of hash output. The "Output Bits" you choose cannot exceed the upper limit of the selected algorithm. The tool will automatically handle out-of-range inputs, usually truncating or reporting an error.
Q: What are the roles of keys and salts? A: Key: mainly used to generate message authentication codes (MAC), to ensure that messages are not tampered with during transmission, and to verify the identity of the sender. Only the recipient with the same key can verify the integrity of the message. Salt: is a random extra data that is combined with the original input before hashing. Its role is to increase the randomness and uniqueness of the hash value, effectively resist rainbow table attacks and pre-computation attacks, even if two users have the same password, different hash values will be generated after salting.
Precautions
Security of keys and salts: Keys and salts are key factors affecting hash security. Please ensure that your keys are complex enough and securely stored to avoid leakage. For salts, it is recommended to use randomly generated, sufficiently long values.
Input data type and encoding: Be sure to select the correct "Input Type" and "Character Encoding" according to your original data. Incorrect settings will cause the hash result to be incorrect. For example, if your data is Hex encoded, but you select "Plaintext", the calculation result will be very different.
Hashing is a one-way process: BLAKE is a hash function, which is a one-way process, meaning that it is impossible to reverse derive the original input string from the hash result. Therefore, it is often used for data integrity verification and password storage, rather than traditional "encryption" for data recovery.
Balance between output bits and security: Choosing the appropriate output bits is important. The longer the number of bits, the lower the probability of hash collisions and the higher the security, but the calculation and storage costs will also increase accordingly. Choose a balance point according to your application scenario.
