HMAC Generator Online-summary

The online HMAC calculation tool supports the hash-based message authentication code calculation based on MD5, SHA1, SHA224, SHA256, SHA384, SHA512, SHA3-256, SHA3-512 and other hash algorithms.

HMAC Generator Online-instructions

HMAC is the abbreviation of Hash-based Message Authentication Code. It is a method of message authentication based on hash function and secret key.

hmac example
  1. Upload File : Calculate the HMAC value of the file, support any type of file, and support 5MB at most. After opening the file, the input type will be automatically set to Hex.
  2. Input Type : Input content type, supports String, Hex, Base64.
  3. Charset : The Secret entered will be converted to a byte array using this character set. If the input type is String, the input content will be converted to a byte array using this character set.
  4. Hash : Hash algorithm, the selected hash algorithm will be used to generate the message authentication code. Currently supported hash algorithms are:MD2, MD4, MD5, SHA1, SHA224, SHA256, SHA384, SHA512, SHA3-224, SHA3-256, SHA3-384, SHA3-512.
  5. Secret : The secret key that generates the hash authentication code.
  6. Result(HEX) : Hexadecimal string representation of HMAC calculation results.
    Result(Base64) : Base64 string representation of HMAC calculation results.
