Hi @startup-dreamer thanks for your PR!

Would you mind adding an additional test here?

foundry/crates/cast/tests/cli/main.rs

Lines 159 to 190 in 1946c2d

	// tests that we can create a new wallet with keystore
	casttest!(new_wallet_keystore_with_password, |_prj, cmd| {
	cmd.args(["wallet", "new", ".", "--unsafe-password", "test"]).assert_success().stdout_eq(str![
	[r#"
	Created new encrypted keystore file: [..]
	[ADDRESS]
	"#]
	]);
	});
	// tests that we can get the address of a keystore file
	casttest!(wallet_address_keystore_with_password_file, |_prj, cmd| {
	let keystore_dir = Path::new(env!("CARGO_MANIFEST_DIR")).join("tests/fixtures/keystore");
	cmd.args([
	"wallet",
	"address",
	"--keystore",
	keystore_dir
	.join("UTC--2022-12-20T10-30-43.591916000Z--ec554aeafe75601aaab43bd4621a22284db566c2")
	.to_str()
	.unwrap(),
	"--password-file",
	keystore_dir.join("password-ec554").to_str().unwrap(),
	])
	.assert_success()
	.stdout_eq(str![[r#"
