implementation
the password is related to the corresponding algorithm
I have this format here: password = [key + 0 + iv/nonce]
| rsa ciphertext length | rsa encrypted password data | algorithm encrypted content | hash value |
|---|---|---|---|
| len(rsa(password)) | rsa(password) | algorithm(content) | hash.Sum(len(rsa(password)) + rsa(password) + algorithm(content)) |
cipher.AEAD
password composition: password = [key + 0 + nonce]
the nonce needs to be taken out correctly, and it must be ensured that there is no 0 in the key
cipher.Stream
password composition: password = [key + 0 + iv]
cipher.BlockMode
password composition: password = [key + 0 + iv]
example
support encryption schemes in golang standard library: cipher.AEAD,cipher.Stream,cipher.BlockMode
at the same time, several encryption schemes of aes are built in: CFB,CTR,OFB,CBC,GCM
// an encryption scheme can be specified with the built-in method
// GenEncCipher(cipher.NewCFBEncrypter)
// GenEncCipher(cipher.NewCTR)
// GenEncCipher(cipher.NewOFB)
// GenEncCipher(cipher.NewCBCEncrypter)
// GenEncCipher(cipher.NewGCM)
EncData(Reader, Writer, pubKey, md5.New(), GenEncCipher(cipher.NewCFBEncrypter))
// an decryption scheme can be specified with the built-in method
// GenDecCipher(cipher.NewCFBDecrypter)
// GenDecCipher(cipher.NewCTR)
// GenDecCipher(cipher.NewOFB)
// GenDecCipher(cipher.NewCBCDecrypter)
// GenDecCipher(cipher.NewGCM)
DecData(Reader, Writer, priKey, md5.New(), GenDecCipher(cipher.NewCFBDecrypter))
you can also refer to GenEncCipher to write the method of generating encryption
you can also refer to GenDecCipher to write the method of generating decryption
