"No such algorithm: 1.2.840.113549.1.5.13" occurs when creating an EncryptedPrivateKey instance.

Hi,

I made a self-signed certificate and produced an encrypted key.pem.
 by using the following command and entering a password:

 $ openssl req -x509 -newkey rsa:2048 -keyout key.pem -outform pem -out cert.pem -days 365

Then, I tried to make the javax.crypto.EncryptedPrivateKeyInfo instance from the above key.pem with the program below,
 by referring to org.bouncycastle.jce.provider.test.EncryptedPrivateKeyInfoTest.java
(I used jdk1.7.0_80 and ***-jdk15on-160.jar)

But "java.security.NoSuchAlgorithmException: No such algorithm: 1.2.840.113549.1.5.13" occured.

As there is also org.bouncycastle.asn1.pkcs.EncryptedPrivateKeyInfo, I tried to use it.

But even in this case,"java.security.NoSuchAlgorithmException: No such algorithm: 1.2.840.113549.1.5.13" occured.

I appreciate if anyone can explain why "No such algorithm: 1.2.840.113549.1.5.13" occurs.

Thanks in advance.
