otPlatCryptoEcdsaExportPublicKey() function

Get the associated public key from the key reference passed. The public key is stored differently depending on the crypto backend library being used (OPENTHREAD_CONFIG_CRYPTO_LIB). This API must make sure to return the public key as a byte sequence representation of an uncompressed curve point (RFC 6605 - sec 4)
