What PGP keys are
Pretty Good Privacy (PGP) keys are used to sign, encrypt, and decrypt files and communications.
To secure sensitive information, we use PGP encryption for:
Batch processing files.
Reports (if configured).
Other files that contain sensitive card data, such as payment data migration files or Account Updater result files.
Updating PGP keys
PGP keys can expire, and you need to ensure that any PGP keys you’ve registered with Adyen are valid and up to date. If a PGP key expires, your ability to process transactions may be affected.
Two weeks before a PGP key expires, we display a message in the System Messages widget of your Customer Area. This message indicates the ID of the expiring key and when it expires. If you subscribe to Account-related system messages, you’ll also receive this message by email.
If you see this message, you'll need to register an updated PGP key with Adyen.
