Unable to decode decrypted string returning null

Question

After decrypting the string using private key, using echo returns value. But when i try to base64_decode its returning null. I needed the value for base64_decode.

openssl_private_decrypt(base64_decode($_POST['data']), $data, $privateKey, OPENSSL_NO_PADDING);

echo $data; // Returning Value --> k/HgB3uQZ1klyeHlJ2jhcG5fSOy+GowIF4bich195ll7zNF9sQbgg/1MkiUpk4ScFlT2e0XIwXzANGgrNi2yEg==
echo base64_decode($data); // returning null

Base64 decoding the string:

The decoded Base64, it is binary data not a string:

In general binary data can not be represented in printable characters and in most cases can not be represented in any character set.

Your String might contain a line break '\n' or some other character that is not decodable in base64, try removing line breaks by using:

str_replace(array("\r", "\n"), '', $data);

(Source: How to remove line breaks (no characters!) from the string?)
