More generally, the openssl command line tool is mostly a proof-of-concept for testing the OpenSSL library. The right answer to this question is either GPG or some archiver such as 7z. – Gilles 'SO- stop being evil' Apr 18 '14 at 12:00.

  1. To use the Run as option, navigate to cmd.exe, usually in the System32 folder, and right-click its icon (or, if you use the command prompt often, as I do, create a shortcut to the program on your.
  2. The above command will generate fileA.txt.enc, fileB.txt.enc, etc, automatically appending.enc extension to the input file names. Decrypting Files from the Terminal Similarly, decryption requires.

Symmetic encryption

For symmetic encryption, you can use the following:

To encrypt:

To decrypt:

Asymmetric encryption

For Asymmetric encryption you must first generate your private key and extract the public key.

To encrypt:

To decrypt:

Encrypting files

You can't directly encrypt a large file using rsautl. Instead, do the following:

  • Generate a key using openssl rand, e.g. openssl rand 32 -out keyfile.
  • Encrypt the key file using openssl rsautl.
  • Encrypt the data using openssl enc, using the generated key from step 1.
  • Package the encrypted key file with the encrypted data. The recipient will need to decrypt the key with their private key, then decrypt the data with the resulting key.

Generate aes key command line commands

What is what:

  • smime — ssl command for S/MIME utility (smime(1)).
  • -encrypt — chosen method for file process.
  • -binary — use safe file process. Normally the input message is converted to 'canonical' format as required by the S/MIME specification, this switch disable it. It is necessary for all binary files (like a images, sounds, ZIP archives).
  • -aes-256-cbc — chosen cipher AES in 256 bit for encryption (strong). If not specified 40 bit RC2 is used (very weak). (Supported ciphers).
  • -in plainfile.zip — input file name.
  • -out encrypted.zip.enc — output file name.
  • -outform DER — encode output file as binary. If is not specified, file is encoded by base64 and file size will be increased by 30%.
  • yourSslCertificate.pem — file name of your certificate's. That should be in PEM format.

That command can very effectively a strongly encrypt any file regardless of its size or format.

Decrypt a file

Decrypt binary file:

For text files:

What is what:

  • -inform DER — same as -outform above.
  • -inkey private.key — file name of your private key. That should be in PEM format and can be encrypted by password.
  • -passin pass:your_password — (optional) your password for private key encrypt.

Bootgen has both a GUI and a command line option. The GUI option is available in the Vitis IDE as a wizard. The functionality in this GUI is limited to the most standard functions when creating a boot image. The Bootgen command line, however, is a full-featured set of commands that lets you create a complex boot image for your system.

Bootgen GUI Options

The Create Boot Image wizard in the Vitis™ GUI offers a limited number of Bootgen options to generate a boot image.

Note: The Bootgen GUI option is not yet supported for Versal™ ACAP.

To create a boot image using the GUI, do the following:

Generate Aes Key Command Line Commands

  1. Select the application project in the Project Navigator or C/C++ Projects view and right-click Create Boot Image. Alternatively, click Xilinx > Create Boot Image.

    The Create Boot Image dialog box opens, with default values pre-selected from the context of the selected C project.

    Note the following:

    • When you run Create Boot Image the first time for an application, the dialog box is pre-populated with paths to the FSBL ELF file, and the bitstream for the selected hardware (if it exists in hardware project), and then the selected application ELF file.
    • If a boot image was run previously for the application, and a BIF file exists, the page is pre-populated with the values from the /bif folder.
    • You can now create a boot image for Zynq®-7000 SoC or Zynq® UltraScale+™ MPSoC architectures.
      IMPORTANT: The data you enter for the boot image should be a maximum of 76 bytes with an offset of 0x4c (for Zynq-7000 SoC) and 40 bytes and an offset of 0x70 (for Zynq UltraScale+ MPSoC). This is a hard limitation based on the Zynq architecture.
  2. Populate the Create Boot Image dialog box with the following information:
    Note: The Vitis GUI wizard is not yet available for Versal devices.
    1. From the Architecture drop-down, select the required architecture.
    2. Select either Create a BIF file or Import an existing BIF file.
    3. From the Basic tab, specify the Output BIF file path.
    4. If applicable, specify the UDF data: See udf_data for more information about this option.
    5. Specify the Output path:
  3. In the Boot image partitions, click the Add button to add additional partition images.
  4. Create offset, alignment, and allocation values for partitions in the boot image, if applicable.

    The output file path is set to the /bif folder under the selected application project by default.

  5. From the Security tab, you can specify the attributes to create a secure image. This security can be applied to individual partitions as required.
    1. To enable authentication for a partition, check the Use Authentication option, then specify the PPK, SPK, PSK, and SSK values. See the Using Authentication topic for more information.
    2. To enable encryption for a partition, select the Encryption view, and check the Use Encryption option. See Using Encryption for more information.
  6. Create or import a BIF file boot image one partition at a time, starting from the bootloader. The partitions list displays the summary of the partitions in the BIF file. It shows the file path, encryption settings, and authentication settings. Use this area to add, delete, modify, and reorder the partitions. You can also set values for enabling encryption, authentication, and checksum, and specifying some other partition related values like Load, Alignment, and Offset.
