for specific usage, please read: EncryptionFile_test.go

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
