decrypt

Description

Decrypts data using the given DecryptDataDetails resource.

The top level –endpoint parameter must be supplied for this operation.

Usage

oci kms crypto decrypt [OPTIONS]

Required Parameters

--ciphertext [text]

The encrypted data to decrypt.

--key-id [text]

The OCID of the key used to encrypt the ciphertext.

Optional Parameters

--associated-data [complex type]

Information that can be used to provide an encryption context for the encrypted data. The length of the string representation of the associated data must be fewer than 4096 characters. This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

--encryption-algorithm [text]

The encryption algorithm to use to encrypt or decrypt data with a customer-managed key. AES_256_GCM indicates that the key is a symmetric key that uses the Advanced Encryption Standard (AES) algorithm and that the mode of encryption is the Galois/Counter Mode (GCM). RSA_OAEP_SHA_1 indicates that the key is an asymmetric key that uses the RSA encryption algorithm and uses Optimal Asymmetric Encryption Padding (OAEP). RSA_OAEP_SHA_256 indicates that the key is an asymmetric key that uses the RSA encryption algorithm with a SHA-256 hash and uses OAEP.

Accepted values are:

AES_256_GCM, RSA_OAEP_SHA_1, RSA_OAEP_SHA_256
--from-json [text]

Provide input to this command as a JSON document from a file using the file://path-to/file syntax.

The --generate-full-command-json-input option can be used to generate a sample json file to be used with this command option. The key names are pre-populated and match the command option names (converted to camelCase format, e.g. compartment-id –> compartmentId), while the values of the keys need to be populated by the user before using the sample file as an input to this command. For any command option that accepts multiple values, the value of the key can be a JSON array.

Options can still be provided on the command line. If an option exists in both the JSON document and the command line then the command line specified value will be used.

For examples on usage of this option, please see our “using CLI with advanced JSON options” link: https://docs.cloud.oracle.com/iaas/Content/API/SDKDocs/cliusing.htm#AdvancedJSONOptions

--key-version-id [text]

The OCID of the key version used to encrypt the ciphertext.

--logging-context [complex type]

Information that provides context for audit logging. You can provide this additional data as key-value pairs to include in audit logs when audit logging is enabled. This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

Example using required parameter

Copy and paste the following example into a JSON file, replacing the example parameters with your own.

    oci kms management key create --generate-param-json-input key-shape > key-shape.json

Copy the following CLI commands into a file named example.sh. Run the command by typing “bash example.sh” and replacing the example parameters with your own.

Please note this sample will only work in the POSIX-compliant bash-like shell. You need to set up the OCI configuration and appropriate security policies before trying the examples.
