示例1: GosaEncryptBuffer
// Replaces the contents of buf with the base64 representation of the data
// after encryption with the given key.
// The key is a word as used in gosa-si.conf whose md5sum will be used as
// the actual AES key. buf is empty, it won't be changed.
func GosaEncryptBuffer(buf *bytes.Buffer, key string) {
datalen := buf.Len()
if datalen == 0 {
return
}
ciph, _ := aes.NewCipher([]byte(util.Md5sum(key)))
crypter := cipher.NewCBCEncrypter(ciph, config.InitializationVector)
cryptpad := (aes.BlockSize - datalen%aes.BlockSize) &^ aes.BlockSize
cryptlen := cryptpad + datalen
b64len := ((cryptlen + 2) / 3) << 2
for i := datalen; i < b64len; i++ {
buf.WriteByte(0)
}
data := buf.Bytes()
copy(data[b64len-datalen:], data) // move data back
idx := b64len - cryptlen
copy(data[idx:], make([]byte, cryptpad)) // insert 0s in front
crypter.CryptBlocks(data[idx:], data[idx:])
util.Base64EncodeInPlace(data, idx)
