golang cryptography library
features/functionality
-
library that provides cryptographic functions and algorithms, including encryption, decryption, hashing, and digital signatures, generation
-
encryption:
-
EncryptAES(key []byte, plaintext []byte) ([]byte, error)
- encrypts the provided plaintext using the AES encryption algorithm
- utilizes AES in CBC mode with a random initialization vector (IV)
-
EncryptDES(key []byte, plaintext []byte) ([]byte, error)
- encrypts the provided plaintext using the DES encryption algorithm
- supports DES encryption for data blocks of the correct size
-
Encrypt3DES(key []byte, plaintext []byte) ([]byte, error)
- encrypts the provided plaintext using the 3DES (Triple DES) encryption algorithm
- requires a 24-byte (192-bit) key
-
-
decryption:
-
DecryptAES(key []byte, ciphertext []byte) ([]byte, error)
- decrypts AES-encrypted ciphertext using the provided key
-
DecryptDES(key []byte, ciphertext []byte) ([]byte, error)
- decrypts DES-encrypted ciphertext using the provided key
-
Decrypt3DES(key []byte, ciphertext []byte) ([]byte, error)
- decrypts 3DES (Triple DES)-encrypted ciphertext using the provided key
-
-
hashing:
-
CalculateSHA256(data []byte) []byte
- calculates the SHA-256 hash of the input data
-
CalculateSHA224(data []byte) []byte
- calculates the SHA-224 hash of the input data
-
CalculateSHA3_256(data []byte) []byte
- calculates the SHA3-256 hash of the input data
-
CalculateSHA1(data []byte) []byte
- calculates the SHA-1 hash of the input data
-
CalculateMD5(data []byte) []byte
- calculates the MD5 hash of the input data
-
CalculateSHA512(data []byte) []byte
- calculates the SHA-512 hash of the input data
-
CalculateSHA384(data []byte) []byte
- calculates the SHA-384 hash of the input data
-
-
randomization:
-
GenerateRandomBytes(length int) ([]byte, error)
- generates a specified number of random bytes
- uses the crypto/rand package for secure random byte generation
-
GenerateRandomHex(length int) (string, error)
- generates a random hexadecimal string of the specified length
- utilizes GenerateRandomBytes internally and encodes the result in hexadecimal
-
-
digital_signatures:
-
GenerateRSAKeyPair(bits int) (rsa.PrivateKey, rsa.PublicKey, error)
- generates an RSA key pair for digital signatures with the specified number of bits
- returns a private key and its corresponding public key
-
SignDataWithRSA(data []byte, privateKey rsa.PrivateKey) ([]byte, error)
- signs a byte array of data using an RSA private key
- uses the PKCS1v15 signature scheme with SHA-256 hash
-
VerifySignatureWithRSA(data, signature []byte, publicKey rsa.PublicKey) error
- verifies a digital signature using an RSA public key
- validates the signature against the data using the PKCS1v15 signature scheme and SHA-256 hash
-
ExportRSAPrivateKeyToPEM(privateKey rsa.PrivateKey) (string, error)
- exports an RSA private key to a PEM-encoded string
-
ExportRSAPublicKeyToPEM(publicKey rsa.PublicKey) (string, error)
- exports an RSA public key to a PEM-encoded string
-
ImportRSAPrivateKeyFromPEM(keyPEM string) (rsa.PrivateKey, error)
- imports an RSA private key from a PEM-encoded string
-
ImportRSAPublicKeyFromPEM(keyPEM string) (rsa.PublicKey, error)
- imports an RSA public key from a PEM-encoded string
-
