The Problem is that the Secret for HMAC must be a HEX. How i can convert ?
Hi, how i can set here the Type of the Secret ? I would like to set it as a hex.
What do you think ?
Thanks,
Stefan
@jan Can you help ?
Finally, is my question how i can set the Keytype to Hex ?
Have sadly honestly no experience there at all. What you can try, if you have a hex-string is to set the Parameter “Secret” to an expression and then to something like:
{{ Buffer.from("YOUR_HEX_STRING", "hex") }}
@Stefan check the workflow below:
{
"nodes": [
{
"parameters": {},
"name": "Start",
"type": "n8n-nodes-base.start",
"typeVersion": 1,
"position": [
250,
360
]
},
{
"parameters": {
"action": "hmac",
"type": "SHA256",
"value": "41791234567",
"secret": "={{Buffer.from('85adf8226953f3d96cfd5d09bf29555eb955fcd8aa5ec4f9fcd869e258370723', 'hex')}}"
},
"name": "Crypto",
"type": "n8n-nodes-base.crypto",
"typeVersion": 1,
"position": [
560,
360
]
}
],
"connections": {
"Start": {
"main": [
[
{
"node": "Crypto",
"type": "main",
"index": 0
}
]
]
}
}
}
Ricardo, that was it !
Thanks a lot !
