ServiceNow SFTP File Encryption

[pramodkumar]

Hi All - We use SFTP Servers for uploading data into ServiceNow via transform maps. How can we encrypt a file in SFTP and Decrypt once received in ServiceNow?

Thanks!

Hi @pramodkumar ,

SFTP will only encrypt the file while it is being transferred. The original file is UN-encrpyted at the sender and recipient host. So only the network transfer is encrypted. If this if good enough according your policy, perfect. Nothing complicated to setup.

HI @pramodkumar ,
I trust you are doing great.

To encrypt a file before uploading it via SFTP and decrypt it once received in ServiceNow, you can follow the steps outlined below:

1. Generate an encryption key:

   • You can use a cryptographic algorithm like AES (Advanced Encryption Standard) to generate a secure encryption key. Ensure the key is strong and kept confidential.

2. Encrypt the file on the SFTP server:

   • Establish a connection to the SFTP server using appropriate credentials.
   • Retrieve the file to be uploaded.
   • Apply the encryption algorithm using the generated encryption key to encrypt the file.
   • Save the encrypted file on the SFTP server.

3. Upload the encrypted file to ServiceNow:

   • Use ServiceNow's SFTP functionality to connect to the SFTP server.
   • Retrieve the encrypted file from the SFTP server.
   • Store the encrypted file in a designated location within ServiceNow, such as a file attachment or a document record.

4. Decrypt the file in ServiceNow:

   • Access the encrypted file stored in ServiceNow.
   • Use the same encryption key that was used to encrypt the file on the SFTP server.
   • Apply the decryption algorithm (AES) using the encryption key to decrypt the file.
   • Ensure the decrypted file is stored securely within ServiceNow.
