Decrypt Field Processor
Description
This processor decrypts a single encrypted string using a defined secret as well as a specified Initialization Vector (IV) field.
Use
Typically you would use the Decrypt processor to remove the encryption applied by the Encrypt processor.
Configuration
The Decrypt processor uses the same configuration options as the Encrypt processor.
| Option | Description | Example |
|---|---|---|
| Field | The field you want to decrypt. | .foo |
| Encryption algorithm | The encryption algorithm to apply. These options also determine how many characters to use for the encryption key and initialization vector. | AES-256-CFB (key=32 characters, iv=16characters) |
| Encryption key | The key used by the algorithm to encrypt the field. | 6B58703273357638792F423F4528482B |
| Initialization vector (IV) field | This value is used by the algorithm as the initialization key. | .encrypt_iv |
Example
Before
{ "encrypt_iv": "FmXUb0OPOWm1A2kw6diKYw==", "foo": "vFza"}Decryption Options
| Option | Value |
|---|---|
