HMAC
The HMAC function card encrypts input text and returns the resulting encrypted text, accepting any HMAC algorithm specified by OpenSSL.
Input
| Field | Definition | Type | Required |
|---|---|---|---|
| algorithm |
OpenSSL encryption algorithms; options are:
|
Dropdown | FALSE |
| key | Text to use as the decryption key; this must be the same key, along with the algorithm, that you used to decrypt. | String | TRUE |
| data |
Encoded text to encrypt.
Only UTF-8 strings are supported. Input string cannot include decimal, binary, hexadecimal, or ASCII characters. |
String | TRUE |
| digest | Digest module used for the encryption; options are base64, hex, and binary. |
Dropdown | FALSE |
Output
| Field | Definition | Type |
|---|---|---|
| output | Encoding of your input data. | String |
Example
If algorithm is sha256, key is my secret key, data is My secret message!, and digest is base64, then output is thNnmggU2ex3L5XXeMNfxf8Wl8STcVZTxscSFEKSxa0=.
The value of the output field can be sent wherever text can be sent. In order to decipher it, you will need to have the correct algorithm and key.
