I am trying to run code with webcrypto but cannot seem to import ECDH public key. What am I missing ?
I get this error: cannot create a key using the specified key usages.

(Works fine on Firefox).
window.crypto.subtle
.generateKey(
{
name: 'ECDH',
namedCurve: 'P-256',
},
true,
['deriveKey', 'deriveBits']
)
.then(function(key) {
return window.crypto.subtle
.exportKey('raw', key.publicKey)
.then(function(ecdhPub) {
return window.crypto.subtle
.importKey(
'raw',
ecdhPub,
{
name: 'ECDH',
namedCurve: 'P-256',
},
false,
['deriveKey', 'deriveBits']
)
.then(function(ecdhPubKey) {
console.log('DONE !!', ecdhPubKey)
})
.catch(function(err) {
console.log('COULD NOT IMPORT...')
console.error(err)
})
})
.catch(function(err) {
console.log('COULD NOT EXPORT...')
console.error(err)
})
})
.catch(function(err) {
console.log('COULD NOT GENERATE KEYS...')
console.error(err)
})
