公司要求對接其他系統，那邊負責人除錯blowfish-ECB成功，但是我在網上看的源代碼加解密都是CBC模式，有沒有大佬有ECB的源代碼？

下面的代碼是blowfish ECB模式加解密，注意假定使用的是 PKCS5Padding, 兩方需要保持一致// https://stackoverflow.com/questions/22733157/java-blowfish-encryption-decryption-bad-padding-exception
public static void main(String[] args) throws Exception {
String mykey="key1";
String text = "this is the secret msg";
SecretKeySpec key = new SecretKeySpec(mykey.getBytes("UTF-8"), "Blowfish");
Cipher cipher = Cipher.getInstance("Blowfish/ECB/PKCS5Padding"); //NoPadding");
if ( cipher == null || key == null) {
throw new Exception("Invalid key or cypher");
}
// encrypt
cipher.init(Cipher.ENCRYPT_MODE, key);
byte[] encrypted = cipher.doFinal(text.getBytes("UTF-8"));
// decrypt
cipher.init(Cipher.DECRYPT_MODE, key);
byte[] plainBytes = cipher.doFinal(encrypted);
String text2 = new String(plainBytes, "UTF-8");
System.out.println(text2);
}

Cipher cipher = Cipher.getInstance("Blowfish/ECB/PKCS5Padding");
檔案從：
https://docs.oracle.com/javase/8/docs/api/javax/crypto/Cipher.html#getInstance-java.lang.String- 繼續找到：
https://docs.oracle.com/javase/8/docs/technotes/guides/security/StandardNames.html#Cipher
Blowfish/ECB/PKCS5Padding 分別從Cipher Algorithm Names， Cipher Algorithm Modes，Cipher Algorithm Padding 中查找
