EVP_PKEY_CTX_gettable_params() and EVP_PKEY_CTX_settable_params() gets a
-constant B<OSSL_PARAM> array that decribes the gettable and
+constant B<OSSL_PARAM> array that describes the gettable and
settable parameters for the current algorithm implementation, i.e. parameters
that can be used with EVP_PKEY_CTX_get_params() and EVP_PKEY_CTX_set_params()
respectively.
