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 is the abbreviation of Hash-based Message Authentication Code. It is a method of message authentication based on hash function and secret key.
- 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.
- Input Type : Input content type, supports String, Hex, Base64.
- 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.
- 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.
- Secret : The secret key that generates the hash authentication code.
-
Result(HEX) : Hexadecimal string representation of HMAC calculation results.
Result(Base64) : Base64 string representation of HMAC calculation results. - This tool has a certain frequency limit, please use this tool reasonably. Anonymous : 30/IP*Hour, Normal user : 30/Hour, VIP : 720/Hour, Senior VIP : 720/Hour.
