AES_DECRYPT

On this page

Decrypts the given ciphertext using the AES (Advanced Encryption Standard) algorithm, with a 128-bit key .

Syntax

AES_DECRYPT(ciphertext, key)

Arguments

  • ciphertext: the binary data to decrypt.

  • key: the text or binary key to use for decryption.

Return Type

The plain text, or NULL if the key does not decrypt the ciphertext .

Remarks

  • Encryption Algorithm: AES

  • Key Size: 128 bit

  • Operation Mode:

    • ECB: Electronic Code Book mode

  • IV (initialization vector): Not used,

Examples

Note: the UNHEX function is used in this example to make it easier to handle binary data.

SELECT AES_DECRYPT(unhex('C958FF3BC0134ADE4A8F952338C1FAEC'), 'ohai');

Verification instructions

Note: You must install cosign to verify the authenticity of the SingleStore file.

Use the following steps to verify the authenticity of singlestoredb-server, singlestoredb-toolbox, singlestoredb-studio, and singlestore-client SingleStore files that have been downloaded.

You may perform the following steps on any computer that can run cosign, such as the main deployment host of the cluster.

  1. (Optional) Run the following command to view the associated signature files.

    curl undefined

  2. Download the signature file from the SingleStore release server.

    • Option 1: Click the Download Signature button next to the SingleStore file.

    • Option 2: Copy and paste the following URL into the address bar of your browser and save the signature file.

    • Option 3: Run the following command to download the signature file.

      curl -O undefined

  3. After the signature file has been downloaded, run the following command to verify the authenticity of the SingleStore file.

    echo -n undefined |
        cosign verify-blob --certificate-oidc-issuer https://oidc.eks.us-east-1.amazonaws.com/id/CCDCDBA1379A5596AB5B2E46DCA385BC \
