Functions ¶
func AesCbcDecrypt ¶ added in v0.0.58
AesCbcDecrypt decrypts cipher text with AES algorithm in CBC mode. Note that key length must be 16, 24 or 32 bytes to select AES-128, AES-192, or AES-256.
func AesCbcDecryptSame ¶ added in v0.0.58
AesCbcDecryptSame decrypts cipher text with AES algorithm in CBC mode. Note that key length must be 16, 24 or 32 bytes to select AES-128, AES-192, or AES-256.
func AesCbcEncrypt ¶ added in v0.0.58
AesCbcEncrypt encrypts data with AES algorithm in CBC mode. Note that key length must be 16, 24 or 32 bytes to select AES-128, AES-192, or AES-256.
func AesCbcEncryptSame ¶ added in v0.0.58
AesCbcEncryptSame encrypts data with AES algorithm in CBC mode. Note that key length must be 16, 24 or 32 bytes to select AES-128, AES-192, or AES-256. This function using the iv from key has security risks so is not recommended to be used. If you want to generate the same ciphertext you can use this func.
func Base64AesCbcDecrypt ¶ added in v0.0.58
Base64AesCbcDecrypt decrypts cipher text encoded by base64 with AES algorithm in CBC mode.
func Base64AesCbcDecryptSame ¶ added in v0.0.58
Base64AesCbcDecryptSame decrypts cipher text encoded by base64 with AES algorithm in CBC mode.
func Base64AesCbcEncrypt ¶ added in v0.0.58
Base64AesCbcEncrypt encrypts data with AES algorithm in CBC mode and then encode using base64.
func Base64AesCbcEncryptSame ¶ added in v0.0.58
Base64AesCbcEncryptSame encrypts data with AES algorithm in CBC mode and then encode using base64.
func Base64DESCBCDecrypt ¶
Base64DESCBCDecrypt decrypts cipher text encoded by base64 with DES algorithm in CBC mode.
func Base64DESCBCEncrypt ¶
Base64DESCBCEncrypt encrypts data with DES algorithm in CBC mode and encoded by base64.
func Base64TriDESCBCDecrypt ¶
Base64TriDESCBCDecrypt decrypts cipher text encoded by base64 with 3DES algorithm in CBC mode.
func Base64TriDESCBCEncrypt ¶
Base64TriDESCBCEncrypt encrypts data with 3DES algorithm in CBC mode and encoded by base64.
func DESCBCDecrypt ¶
DESCBCDecrypt decrypts cipher text with DES algorithm in CBC mode. Note that key length must be 8 bytes.
func DESCBCEncrypt ¶
DESCBCEncrypt encrypts data with DES algorithm in CBC mode. Note that key length must be 8 bytes.
func GenRsaKey ¶
GenRsaKey generates an PKCS#1 RSA keypair of the given bit size in PEM format. Common key bit size include 1024, 2048, 3072 and 4096 bits etc. Note 2048 bits is the current recommended standard, and 3072 bits and 4096 bits are suitable for situations where higher security is required.
func HMAC ¶
HMAC generates authentication code based on specified hash algorithm. e.g. HMAC("", "", "MD5", false) returns 74e6f7298a9c2d168935f58c001bad88.
func HMACMD5 ¶
HMACMD5 generates 32 uppercase hexadecimal characters authentication code based on MD5.
func HMACMd5 ¶
HMACMd5 generates 32 lowercase hexadecimal characters authentication code based on MD5.
func HMACSHA1 ¶
HMACSHA1 generates 40 uppercase hexadecimal characters authentication code based on SHA1.
func HMACSHA224 ¶

HMACSha384 generates 96 lowercase hexadecimal characters authentication code based on SHA384.
func HMACSha512 ¶
HMACSha512 generates 128 lowercase hexadecimal characters authentication code based on SHA512.
func Hash ¶
Hash generates a checksum of the specified hash algorithm. E.g. Hash("", "MD5", false) returns d41d8cd98f00b204e9800998ecf8427e.
func PKCS7Padding ¶
PKCS7Padding fills plaintext as an integral multiple of the block length. In cryptography, PKCS stands for "Public Key Cryptography Standards". These are a group of public key cryptography standards devised and published by RSA Security LLC, starting in the early 1990s. PKCS#7 is Cryptographic Message Syntax Standard used to sign and/or encrypt messages under a PKI. More information about PKCS#7 please refer to the RFC 2315. The PKCS#7 padding method works by adding bytes that all have the same value as the number of bytes added to the plaintext. For example, if the last block of plaintext is 3 bytes long and the block size is 8 bytes, then 5 bytes of padding are added to make the total length of the plaintext 8 bytes. The value of the 5 bytes will be the hex value 0x05, since 5 bytes were added as padding.
func PKCS7UnPadding ¶
PKCS7UnPadding removes padding data from the tail of plaintext.
func RsaDecrypt ¶
RsaDecrypt decrypts data using rsa private key.
func RsaEncrypt ¶
RsaEncrypt encrypts data using rsa public key.
func RsaVerifySign ¶
RsaVerifySign verifies signature using public key in PEM format. A valid signature is indicated by returning a nil error.

func TriDESCBCEncrypt ¶
TriDESCBCEncrypt encrypts data with 3DES algorithm in CBC mode. Note that key length must be 24 bytes
