HMAC-SHA256 Hash Tool Documentation

The HMAC-SHA256 Hash Tool is a tool used to generate HMAC-SHA256 hash values. It can hash the input string and key to generate the corresponding HMAC-SHA256 hash value, and output it in HEX or BASE64 format.

Function Description:

1. Enter the string to be hashed in the input box.

2. If you need to use a key for hashing, enter the key in the key input box.

3. Select the output format, you can choose HEX or BASE64 format.

4. You can choose whether to add a separator and the type of separator.

5. You can choose whether to convert the output result to uppercase or lowercase.

6. The output result will be displayed in the output area of the tool.

7. You can use the comparison function to compare the output result with another string to determine if they are the same.

Use Cases:

1. Data Encryption: When encrypting data, you can use the HMAC-SHA256 Hash Tool to generate HMAC-SHA256 hash values to ensure data security.

2. API Development and Testing: When developing or testing APIs, developers often need to hash data. Using the HMAC-SHA256 Hash Tool can quickly and easily generate HMAC-SHA256 hash values.

3. Data Verification: When verifying data, you can use the HMAC-SHA256 Hash Tool to generate HMAC-SHA256 hash values and compare them with the expected hash values to determine if the data has been tampered with.

4. Security Audit: When conducting security audits, you can use the HMAC-SHA256 Hash Tool to generate HMAC-SHA256 hash values to check if the data in the system has been tampered with.
