Hi Team,

I want to decipher a cipher text using logstash. My client is using AES128 encryption. So in logstash I am using cipher filter to decipher the ciphertext. They have also provided me the key , but unfortunately only about 70% percent of my ciphertext is getting deciphered , full cipher text is not getting decrypted

Please help me
