I'm only interested in the technical part of decrypting AES-CBC in go:
Code:
encKey := doubleSHA([]byte("password"))
ciphertext, err := base64.StdEncoding.DecodeString("***base64 string from the wallet***")
if err != nil {
panic(err)
}
block, err := aes.NewCipher(encKey)
if err != nil {
panic(err)
}
blockSize := block.BlockSize()
iv := ciphertext[:blockSize]
ciphertext = ciphertext[blockSize:]
if len(ciphertext)%blockSize != 0 {
panic("ciphertext is not a multiple of the block size")
}
mode := cipher.NewCBCDecrypter(block, []byte(iv))
mode.CryptBlocks(ciphertext, ciphertext)
fmt.Printf("%s\n", ciphertext)
ciphertext, err := base64.StdEncoding.DecodeString("***base64 string from the wallet***")
if err != nil {
panic(err)
}
block, err := aes.NewCipher(encKey)
if err != nil {
panic(err)
}
blockSize := block.BlockSize()
iv := ciphertext[:blockSize]
ciphertext = ciphertext[blockSize:]
if len(ciphertext)%blockSize != 0 {
panic("ciphertext is not a multiple of the block size")
}
mode := cipher.NewCBCDecrypter(block, []byte(iv))
mode.CryptBlocks(ciphertext, ciphertext)
fmt.Printf("%s\n", ciphertext)
