Functions ¶
func AesCBCDecrypt ¶
AesCBCDecrypt decrypt data use AES/CBC/PKCS5
key: 16 or 24 or 32 length secret key is required
iv : 16 length iv is required
Example ¶
enc, _ := AesCBCEncrypt([]byte("hello"), []byte("1234567812345678"), []byte("1234567812345678"))
dec, err := AesCBCDecrypt(enc, []byte("1234567812345678"), []byte("1234567812345678"))
if err != nil {
panic(err)
}
fmt.Printf("%s", dec)
Output:
func AesCBCEncrypt ¶
AesCBCEncrypt encrypt data use AES/CBC/PKCS5
key: 16 or 24 or 32 length secret key is required
iv : 16 length iv is required
Example ¶
enc, err := AesCBCEncrypt([]byte("hello"), []byte("1234567812345678"), []byte("1234567812345678"))
if err != nil {
panic(err)
}
fmt.Printf("%x", enc)
fmt.Printf("%s", hex.EncodeToString(enc))
Output:
func AesCTRDecryptFile ¶
AesCTRDecryptFile decrypt file use AES/CTR
key: 16 or 24 or 32 length secret key is required
iv : 16 length iv is required
Example ¶
err := AesCTRDecryptFile("originFilename", "targetFilename", _testKey.Length32[4], _testIv[1])
if err != nil {
panic(err)
}
Output:
func AesCTRDecryptFileIO ¶
AesCTRDecryptFileIO decrypt file use AES/CTR
key: 16 or 24 or 32 length secret key is required
iv : 16 length iv is required
Example ¶
inFile, _ := os.Open("originFilename")
outFile, _ := os.Create("targetFilename")
err := AesCTRDecryptFileIO(inFile, outFile, _testKey.Length32[4], _testIv[1])
if err != nil {
panic(err)
}
Output:
func AesCTREncryptFile ¶
AesCTREncryptFile encrypt file use AES/CTR
key: 16 or 24 or 32 length secret key is required
iv : 16 length iv is required
Example ¶
err := AesCTREncryptFile("originFilename", "targetFilename", _testKey.Length32[4], _testIv[1])
if err != nil {
panic(err)
}
Output:
func AesCTREncryptFileIO ¶
AesCTREncryptFileIO encrypt file use AES/CTR
key: 16 or 24 or 32 length secret key is required
iv : 16 length iv is required
Example ¶
inFile, _ := os.Open("originFilename")
outFile, _ := os.Create("targetFilename")
err := AesCTREncryptFileIO(inFile, outFile, _testKey.Length32[4], _testIv[1])
if err != nil {
panic(err)
}
Output:
func CBCBlockMode ¶
CBCBlockMode create a CBC cipher.BlockMode use key and iv
key: 16 or 24 or 32 length secret key is required
iv : 16 length iv is required
encrypt: if true return a encrypt cipher.BlockMode. else return a decrypt cipher.BlockMode
