I'm trying to add a test case for my function which is extracting key from the local Keystore.

This is how I'm creating an instance of a local Keystore and setting a key inside it in my test environment:

let keystore = LocalKeystore::in_memory();
SyncCryptoStore::insert_unknown(&keystore, KeyTypeId::try_from("test").unwrap(), "test", public_key);

Here the problem I'm facing is, I'm unable to extract the stored key from the keystone. This is how I'm extracting it:

SyncCryptoStore::sr25519_public_keys(&keystore, KeyTypeId::try_from("test").unwrap())

This function is returning an empty vector.

You can check the key existance with has_key method and list all available keys with keys. the sr25519_public_keys method forces to retrieve just the sr25519 ones.

  • I'm getting sr25519 in my list but still, this function is returning an empty vector. –

  • you have created public_key somewhere that maybe is not true sr25519 please use sr25519_generate_new instead and iterate over all sr25519 keys by sr25519_public_keys

  • I was converting the public key into bytes using .as_bytes(), but after converting it using sp_core::sr25519::Public:: from_ss58check(), the problem got resolved. Converting a string of public key into bytes using .as_bytes() is the wrong approach, in substrate we should convert the keys into bytes using the substrate's internal components only. Thanks for your help.
