Request parameters

Parameter	Type	Required	Description	Example
Plaintext	string	Yes	The data that you want to encrypt. The value of this parameter can be raw data or Base64-encoded data. For more information, see the description of the MessageType parameter. For example, if the hexadecimal data that you want to encrypt is `[0x31, 0x32, 0x33, 0x34]`, the Base64-encoded data is MTIzNA==. The size of data that can be encrypted varies based on the encryption algorithm that you use. The following list describes the relationship between the encryption algorithms and data sizes: RSAES_OAEP_SHA_1: 214 bytes RSAES_OAEP_SHA_256: 190 bytes SM2PKE: 6,047 bytes	1234***
CertIdentifier	string	Yes	The unique identifier of the certificate. You can call the ListCert operation to obtain the identifier. If the certificate is an SSL certificate, the value of this parameter must be in the {Certificate ID}-cn-hangzhou format. If the certificate is a private certificate, the value of this parameter must be the value of the Identifier field for the private certificate.	12345678-1234-1234-1234-12345678****
Algorithm	string	Yes	The encryption algorithm. Valid values: RSAES_OAEP_SHA_1 RSAES_OAEP_SHA_256 SM2PKE	RSAESOAEPSHA_1
MessageType	string	No	The value type of the Message parameter. Valid values: RAW: The value of the Plaintext parameter is directly encrypted. This is the default value. Base64: The value of the Plaintext parameter is Base64-encoded data. The data is decoded and then encrypted.	RAW

Response parameters
