  • 1.  Decrypt the encrypted data in Datapower.

    Posted Mon October 31, 2022 11:19 AM
    Hi,

    Data is encrypted in Java Application.
    To decrypt the data using the below code in Datapower.

    1. Provided the private key to decrypt the data
    2. Receiving the secretKey in the encrypted response
    3. Below is the XSLT code to decrypt the data.



    <xsl:variable name="RSAAlg" select="'http://www.w3.org/2001/04/xmlenc#rsa-1_5'"/>
    <xsl:variable name="privateKey" select="'name:crypto-key-pass'"/>
    <xsl:variable name="secretKeyEncrypted" select="//*[local-name()='secretKey']"/>

    <xsl:variable name="secretKeyDecrypted">
    <xsl:value-of select="dp:decrypt-key($secretKeyEncrypted,$privateKey,$RSAAlg)"/>
    </xsl:variable>

    <xsl:variable name="vAlgorithm" select="'http://www.w3.org/2001/04/xmlenc#aes128-cbc'"/>
    <xsl:variable name="encryptedtext" select="//*[local-name()='companyType']"/>

    <xsl:variable name="vDecrypt">
    <xsl:value-of select="dp:decrypt-data($vAlgorithm,$secretKeyDecrypted,$encryptedtext)"/>
    </xsl:variable>
    <decryptedResponse>

    Getting the below error while executing the xslt code.

    mpgw: Ephemeral key decryption failed: *RSA decryption failed*
    mpgw: *RSA decryption failed*

    Could you please help on the below issue

    do you have any more log details, I presume your crypto object "crypto-key-pass" is up in the datapower ?
    Could you maybe make a corresponding encryption as well in the same XSLT, just to make sure the keypair matches ? (so encrypt and decrypt directly after)
