IR.CreateEncryption()

Create an encryption object

Syntax
RSA:

IR.CreateEncryption(encryption_type, key_size)

IR.CreateEncryption(encryption_type, key, is_public)

AES:

IR.CreateEncryption(encryption_type, AES_object)

on the input	value	description
encryption_type	IR.ENCRYPTION_RSA, IR.ENCRYPTION_AES	type: Object Type of encryption.
key_size	32(256 bit), 64(512 bit), 128(1024 bit), 256(2048 bit), 512(4096 bit)	type: Number The size of a key in bytes.
key	"60,25,57,21,96,..."	type: String Key.
is_public	true	type: Boolean true - a public key, false - a private key.
AES_object	l_AESInit = {"Vector": "56,2e,17, ...", "Key": "60,25,57, ..."}	type: Object Encryption data.
on the output
Object	[object EnctyptionPrototype]	type: Object Encryption object.

//////////////RSA encryption object.////////////////
//Creating an encryption object with a 128-byte key:
var RSA_1 = IR.CreateEncryption(IR.ENCRYPTION_RSA, 128); 
 
 
var public_key = RSA_1.GetPublicKey(); // getting a public key
//Creating an encyrption object with the help of a public key:

.Encode()

Encrypt a string or data array.

Syntax

IR.CreateEncryption(param).Encode(data, resultType, inputType)

on the input	value	description
data	"3,0,0,0,0, ..."	type: String / Array Encryption data.
resultType	IR.RESULT_TYPE_ARRAY, IR.RESULT_TYPE_BASE64_STRING*	type: String / Array Type of encrypted value.
inputType**	IR.INPUT_TYPE_BYTE_STRING, IR.INPUT_TYPE_BASE64_STRING	type: String Type of parameter data.
on the output
EncryptedData	"246,75,186,52,183, ..."	type: String / Array Encrypted data.

// Encrype data with base64 result
var encode_base64 = RSA_2.Encode(data, IR.RESULT_TYPE_BASE64_STRING); 
IR.Log("BASE64 ENCODE: " + encode_base64);

* You can get a string in the Base64 format not to lose data.
**Active only with a data string.

.Decode()

Decrypt a string or data array.

Syntax

EncryptedData.Decode(data, resultType, inputType)

on the input	value	description
data	"246,75,186,52,183, ..."	type: String / Array Encrypted data.
resultType	IR.RESULT_TYPE_ARRAY, IR.RESULT_TYPE_STRING, IR.RESULT_TYPE_BASE64_STRING*	type: String / Array Type of encrypted value.
inputType**	IR.INPUT_TYPE_BYTE_STRING, IR.INPUT_TYPE_BASE64_STRING	type: String Type of parameter data.
on the output
DecryptedData	"3,0,0,0,0, ..."	type: String / Array Decrypted data.

// Decrypt encode_base64 with a string result:
var decode_string_1 = RSA_1.Decode(encode_base64, IR.RESULT_TYPE_STRING, IR.INPUT_TYPE_BASE64_STRING); 
IR.Log("STRING DECODE_FROM_BASE64: " + decode_string_1);

* You can get a string in the Base64 format not to lose data.
**Active only with a data string.

.GetPublicKey()

Get a public key.

Syntax

EncryptedData.GetPublicKey()

input

value

description

EncryptedData

"246,75,186,52,183, ..."

type: String / Array Encrypted data.

output

PublicKey

"60,25,57,21,96,..."

type: String A public key.

Sample

// Initialization of an encryption object.
var RSA_1 = IR.CreateEncryption(IR.ENCRYPTION_RSA, 128);
//Getting a public key
var public_key = RSA_1.GetPublicKey();
IR.Log("public key: " + public_key);

This method works only with RSA encryption.
