Encrypts data, so that it can only be recovered by a call to Decrypt. The CryptoKey.purpose must be ENCRYPT_DECRYPT.

post/v1/{+name}:encrypt

Path parameters

namestring required

Required. The resource name of the CryptoKey or CryptoKeyVersion to use for encryption. If a CryptoKey is specified, the server will use its primary version.

Request body

plaintextCrc32cstring int64

Optional. An optional CRC32C checksum of the EncryptRequest.plaintext. If specified, KeyManagementService will verify the integrity of the received EncryptRequest.plaintext using this checksum. KeyManagementService will report an error if the checksum verification fails. If you receive a checksum error, your client should verify that CRC32C(EncryptRequest.plaintext) is equal to EncryptRequest.plaintext_crc32c, and if so, perform a limited number of retries. A persistent mismatch may indicate an issue in your computation of the CRC32C checksum. Note: This field is defined as int64 for reasons of compatibility across different languages. However, it is a non-negative integer, which will never exceed 2^32-1, and can be safely downconverted to uint32 in languages that support this type.

additionalAuthenticatedDatastring byte

Optional. Optional data that, if specified, must also be provided during decryption through DecryptRequest.additional_authenticated_data. The maximum size depends on the key version's protection_level. For SOFTWARE, EXTERNAL, and EXTERNAL_VPC keys the AAD must be no larger than 64KiB. For HSM keys, the combined length of the plaintext and additional_authenticated_data fields must be no larger than 8KiB.

additionalAuthenticatedDataCrc32cstring int64

Optional. An optional CRC32C checksum of the EncryptRequest.additional_authenticated_data. If specified, KeyManagementService will verify the integrity of the received EncryptRequest.additional_authenticated_data using this checksum. KeyManagementService will report an error if the checksum verification fails. If you receive a checksum error, your client should verify that CRC32C(EncryptRequest.additional_authenticated_data) is equal to EncryptRequest.additional_authenticated_data_crc32c, and if so, perform a limited number of retries. A persistent mismatch may indicate an issue in your computation of the CRC32C checksum. Note: This field is defined as int64 for reasons of compatibility across different languages.
