Class Detail

KJUR.crypto.Cipher(params)

Cipher class to encrypt and decrypt data
Here is supported canonicalized cipher algorithm names and its standard names:

aes256-CBC
aes128-CBC
des-EDE3-CBC

NOTE: From jsrsasign 11.0.0, RSA and RSAOAEP encryption/decryption support is removed because of Marvin attack vulnerability.

Parameters:
{Array} params: parameters for constructor

Since:: jsrsasign 6.2.0 crypto 1.1.10

Method Detail

<static> {string} KJUR.crypto.Cipher.decrypt(hex, hexadecimal, algName, param)

decrypt encrypted hexadecimal string with specified key and algorithm
This static method decrypts encrypted hexadecimal string with specified key and algorithm.
NOTE: From jsrsasign 10.9.0, asymmetric cipher ({des-EDE3,aes{128,256}}-CBCis also supported. NOTE2: From jsrsasign 11.0.0, RSA and RSAOAEP encryption/decryption support is removed because of Marvin attack vulnerability.

KJUR.crypto.Cipher.decrypt("12abcd...", "5a7d...", "aes256-CBC", { iv: "1b3c..." }) 
KJUR.crypto.Cipher.decrypt("12abcd...", "5a7d...", any, { encalg: "aes128-CBC", iv: "1b3c..." }) 
KJUR.crypto.Cipher.decrypt("12abcd...", any, any, { encalg: "des-EDE3-CBC", iv: "1b3c...", key: "3d41..." }) 
KJUR.crypto.Cipher.decrypt(any, any, any, { encalg: "des-EDE3-CBC", iv: "1b3c...", key: "3d41...", enc: "12abcd..." })

Parameters:
{string} hex: hexadecimal string of encrypted message
{object} hexadecimal: string of symmetric cipher key
{string} algName: short/long algorithm name for encryption/decryption (OPTION)
{object} param: parameters for synchronous cipher such as initial vector (OPTION)

Since:: jsrsasign 6.2.0 crypto 1.1.10

Returns:: {string} decrypted raw string

<static> {string} KJUR.crypto.Cipher.encrypt(s, hexadecimal, algName, param)

encrypt raw string by specified key and algorithm
This static method encrypts raw string with specified key and algorithm.
NOTE: From jsrsasign 10.9.0, asymmetric cipher ({des-EDE3,aes{128,256}}-CBC) is also supported. NOTE2: From jsrsasign 11.0.0, RSA and RSAOAEP encryption/decryption support is removed because of Marvin attack vulnerability.

KJUR.crypto.Cipher.encrypt("12abcd...", "5a7d...", "aes256-CBC", { iv: "1b3c..." }) 
KJUR.crypto.Cipher.encrypt("12abcd...", "5a7d...", any, { encalg: "aes128-CBC", iv: "1b3c..." }) 
KJUR.crypto.Cipher.encrypt("12abcd...", any, any, { encalg: "des-EDE3-CBC", iv: "1b3c...", key: "3d41..." }) 
KJUR.crypto.Cipher.encrypt(any, any, any, { encalg: "des-EDE3-CBC", iv: "1b3c...", key: "3d41...", enc: "12abcd..." })

Parameters:
{string} s: input string to encrypt
{string} hexadecimal: string of symmetric cipher key
{string} algName: short/long algorithm name for encryption/decryption (OPTION)
{object} param: parameters for synchronous cipher such as initial vector (OPTION)

Since:: jsrsasign 6.2.0 crypto 1.1.10

Returns:: {string} hexadecimal encrypted string
