Error message when decrypting Private Key for SnowFlake : java.lang.NoClassDefFoundError: org/bouncycastle/openssl/PEMParser

Hi All,

I am currently trying to retrieve an encrypted private key for SnowFlake from Azure Key Vault.

I have build all the components needed to retrieve the key from AKV but now I am facing an issue while reading the key. (i have follow the instruction here Qlik Talend key pair authentication with Snowflake via Azure Key Vault | by Archan Chatterjee | Medium, which were great)

Because it is encrypted with a non natively supported encryption from OpenSSL, I need to decrypt it before sending it to my Keystore using BouncyCastle.

My code in error is the following :

Security.addProvider(new BouncyCastleProvider()); //Restaurer le format PEM complet (header/footer + lignes normales) String pemFormattedPrivateKey = "-----BEGIN ENCRYPTED PRIVATE KEY-----\n" + base64PrivateKey.replaceAll("(.{64})", "$1\n") + "\n" + "-----END ENCRYPTED PRIVATE KEY-----"; //Utiliser PEMParser pour parser la clé PEMParser pemParser = new PEMParser(new StringReader(pemFormattedPrivateKey)); Object parsedObject = pemParser.readObject(); pemParser.close(); PKCS8EncryptedPrivateKeyInfo encryptedPrivateKeyInfo = (PKCS8EncryptedPrivateKeyInfo) parsedObject; InputDecryptorProvider decryptorProvider = new JceOpenSSLPKCS8DecryptorProviderBuilder().build(password); PrivateKeyInfo privateKeyInfo = encryptedPrivateKeyInfo.decryptPrivateKeyInfo(decryptorProvider); PrivateKey privateKey = new JcaPEMKeyConverter() .setProvider("BC") .getPrivateKey(privateKeyInfo);

What Studio seems to doesn't like is this line :

PEMParser pemParser = new PEMParser(new StringReader(pemFormattedPrivateKey));

The error is :

Exception in thread "main" java.lang.NoClassDefFoundError: org/bouncycastle/openssl/PEMParser

I have done everything requiered:

Added the requiered librairies:

import org.bouncycastle.asn1.pkcs.PrivateKeyInfo; import org.bouncycastle.openssl.PEMParser; import org.bouncycastle.openssl.jcajce.JcaPEMKeyConverter; import org.bouncycastle.openssl.jcajce.JceOpenSSLPKCS8DecryptorProviderBuilder; import org.bouncycastle.pkcs.PKCS8EncryptedPrivateKeyInfo; import org.bouncycastle.operator.InputDecryptorProvider; import org.bouncycastle.jce.provider.BouncyCastleProvider; import java.io.StringReader; import java.security.Security;

Updated the Maven Project :

<dependencies>  <dependency> <groupId>org.bouncycastle</groupId> <artifactId>bcprov-jdk18on</artifactId> <version>1.78.1</version> </dependency>  <dependency> <groupId>org.bouncycastle</groupId> <artifactId>bcpkix-jdk18on</artifactId> <version>1.78.1</version> </dependency> </dependencies>

Checked if the Jar are in the Module section (all ok).

But nothing worked.

Do you have any idea what could be the issue ?

Thanks

Hello,

Where did you put your java code ?
in a tJava component ?
In a Routine ?

Kind regards
Denis

Hi Denis,

The code is in a tJavaRow component.

Hello Laurent,
Did you test to add a tLibraryLoad (or several) in order to "load" the librarie(s) (jar file(s)) containing the Java classes used in the tJavaRow ?

Kind regards
Denis
