Decrypt Field Processor

Description

This processor decrypts a single encrypted string using a defined secret as well as a specified Initialization Vector (IV) field.

Typically you would use the Decrypt processor to remove the encryption applied by the Encrypt processor.

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`

{
  "encrypt_iv": "FmXUb0OPOWm1A2kw6diKYw==",
  "foo": "vFza"
}

Option	Value
Field	`.foo`
Decryption algorithm	`AES-256-CFB (key=32 characters, iv=16characters)`
Decryption key	`6B58703273357638792F423F4528482B`
Initialization vector (IV) field	`.encrypt_iv`

{
  "encrypt_iv": "FmXUb0OPOWm1A2kw6diKYw==",
  "foo": "bar"
}
