gcry

Lib that abstracts the encryption algorithms used by golang.

The goal is to further facilitate the native ualization of existing libs in Go.

We use numbers like CBC, CFB, GCM, OFB, MD5, BLOWFISH etc.

Using EncryptGCM

package main

import (
	"fmt"
	gcry "github.com/jeffotoni/gcry"
)

fsunc main() {

	textCry := gcry.EncryptGCM("Let's encrypt our text here.")
	fmt.Println(textCry)

	textDescry := gcry.DecryptGCM(textCry)
	fmt.Println(textDescry)
}

Using EncryptCFB

package main

import (
	"fmt"
	gcry "github.com/jeffotoni/gcry"
)

//
//
//
func main() {

	cipherText := gcry.EncryptCFB("new functional ex: of crifra CFB ")

	fmt.Println(cipherText)

	textplan := gcry.DecryptCFB(cipherText)
	fmt.Println(textplan)
}

Using EncryptCBC

package main

import (
	"fmt"
	gcry "github.com/jeffotoni/gcry"
)

//
//
//
func main() {

	// multiple 16 len text
	cipherText := gcry.EncryptCBC("new functional ex: of crifra CBC")

	fmt.Println(cipherText)

	textplan := gcry.DecryptCBC(cipherText)

	fmt.Println(textplan)
}

Using Uid Rand

package main

import (
	"fmt"
	gcry "github.com/jeffotoni/gcry"
)

func main() {

	fmt.Println(gcry.UidRand())
}

Using Sha1

package main

import (
	"fmt"
	gcry "github.com/jeffotoni/gcry"
)

func main() {

	password := "1234567890#$"

	hash := gcry.Sha1(password)

	fmt.Println(hash)
}

Using Blowfish

package main

import (
	"fmt"
	gcry "github.com/jeffotoni/gcry"
)

func main() {

	password := "1234567890#$"

	hashBlo := gcry.Blowfish(password)

	if gcry.CheckBlowfish(password, hashBlo) {

		fmt.Println("ok, password correct!")

	} else {

		fmt.Println("ok, password incorrect!")
	}

}

Using Blowfish Uid

package main

import (
	"fmt"
	gcry "github.com/jeffotoni/gcry"
)

func main() {

	fmt.Println(gcry.BlowfishUid())
}

Using HashFile

package main

import (
	"fmt"
	gcry "github.com/jeffotoni/gcry"
)

func main() {

	hash, _ := gcry.HashFile("main-cbc.go")
	fmt.Println(hash)
}

Using Sha256

package main

import (
	"fmt"
	gcry "github.com/jeffotoni/gcry"
)

func main() {

	password := "1234567890#$"

	hash := gcry.Sha256(password)
}

Using OFB File

It is possible to encrypt files, ie your content will be encrypted and generated a new file.

package main

import (
	"fmt"
	gcry "github.com/jeffotoni/gcry"
)

func main() {
	
	fileCry := gcry.EncryptOFBFile("main-cbc.go")

	fmt.Println(fileCry)

	fileDecry := gcry.DecryptOFBFile(fileCry)

	fmt.Println(fileDecry)
}
