SignPKCS1v15 in Go
by GoDoc Go crypto/rand crypto crypto.SHA256 crypto/sha256 fmt
SignPKCS1v15 calculates the signature of hashed using RSASSA-PKCS1-V1_5-SIGN from RSA PKCS#1 v1.5. Note that hashed must be the result of hashing the input message using the given hash function. If hash is zero, hashed is signed directly. This isn't advisable except for interoperability.
EncryptOAEP in Go
by GoDoc Go crypto/rand crypto/sha256 fmt fmt.Fprintf fmt.Printf
EncryptOAEP encrypts the given message with RSA-OAEP.
DecryptPKCS1v15SessionKey in Go
by GoDoc Go crypto/rand fmt.Fprintf hex.DecodeString os.Stderr aes.NewCipher
DecryptPKCS1v15SessionKey decrypts a session key using RSA and the padding scheme from PKCS#1 v1.5. If rand != nil, it uses RSA blinding to avoid timing side-channel attacks. It returns an error if the ciphertext is the wrong length or if the ciphertext is greater than the public modulus. Otherwise,...
DecryptOAEP in Go
by GoDoc Go crypto/rand crypto/sha256 encoding/hex fmt fmt.Fprintf
DecryptOAEP decrypts ciphertext using RSA-OAEP.
Read in Go
by GoDoc Go crypto/rand fmt.Println bytes bytes.Equal fmt
This example reads 10 cryptographically secure pseudorandom numbers from rand.Reader and writes them to a byte slice.
Using crypto/ecdsa in Go
by GoDoc Go crypto/rand rand.Reader crypto/ecdsa crypto/elliptic crypto/sha256
Package ecdsa implements the Elliptic Curve Digital Signature Algorithm, as defined in FIPS 186-3.
NewOFB in Go
by GoDoc Go crypto/rand aes.BlockSize cipher.NewOFB aes.NewCipher crypto/aes
NewOFB returns a Stream that encrypts or decrypts using the block cipher b in output feedback mode. The initialization vector iv's length must be equal to b's block size.
NewGCM (Encrypt) in Go
by GoDoc Go crypto/rand aes.NewCipher cipher.NewGCM crypto/aes crypto/cipher
NewGCM returns the given 128-bit, block cipher wrapped in Galois Counter Mode with the standard nonce length.
NewCTR in Go
by GoDoc Go crypto/rand aes.BlockSize cipher.NewCTR aes.NewCipher crypto/aes
NewCTR returns a Stream which encrypts/decrypts using the given Block in counter mode. The length of iv must be the same as the Block's block size.
NewCFBEncrypter in Go
by GoDoc Go crypto/rand aes.BlockSize aes.NewCipher cipher.NewCFBEncrypter crypto/aes
NewCFBEncrypter returns a Stream which encrypts with cipher feedback mode, using the given Block. The iv must be the same length as the Block's block size.
NewCBCEncrypter in Go
by GoDoc Go crypto/rand aes.BlockSize aes.NewCipher cipher.NewCBCEncrypter crypto/aes
NewCBCEncrypter returns a BlockMode which encrypts in cipher block chaining mode, using the given Block. The length of iv must be the same as the Block's block size.
