    Encryption and Decryption test using certificate '5D48CF33494CDE412DE69F58D67B22003E087B39' failed!

    Steps i followed

    a- New-SelfSignedCertificate -Type Custom -Provider "Microsoft Strong Cryptographic Provider" -DnsName "xxx.xx.com" -CertStoreLocation "Cert:\LocalMachine\My"

    Sucessfully created.

    b- Changed all the parameters in the encryptdata ps file by running the following commands

     .\gacutil.exe -l | findstr WorkflowActivityLibrary

    updating the correct thumbprint

    c- Updating the password i want to encrypt.

    d- Running the command encryptdata_xx.ps1 gives the error.

    Powershell version is  4.6 or above. Not sure what the error is as the output file is correctly generated with the correct format
