Simple cryptography API in Go

1. Hashes:

   • hash.MD5Bytes, hash.MD5Base64, hash.MD5Hex
     calculates an MD5 chechsum of the input byte array as a byte array, base64-encoded string or hex-encoded string

   • hash.SHA1Bytes, hash.SHA1Base64, hash.SHA1Hex
     calculates an SHA1 chechsum of the input byte array as a byte array, base64-encoded string or hex-encoded string

   • hash.SHA224Bytes, hash.SHA224Base64, hash.SHA224Hex
     calculates an SHA-224 chechsum of the input byte array as a byte array, base64-encoded string or hex-encoded string

   • hash.SHA256Bytes, hash.SHA256Base64, hash.SHA256Hex
     calculates an SHA-256 chechsum of the input byte array as a byte array, base64-encoded string or hex-encoded string

   • hash.SHA384Bytes, hash.SHA384Base64, hash.SHA384Hex
     calculates an SHA-384 chechsum of the input byte array as a byte array, base64-encoded string or hex-encoded string

   • hash.SHA512Bytes, hash.SHA512Base64, hash.SHA512Hex
     calculates an SHA-512 chechsum of the input byte array as a byte array, base64-encoded string or hex-encoded string

2. Password-based (PB):

   • pb.PBAesEncrypt encrypts input byte array using string password specified into a new (encrypted) byte array

   • pb.PBAesDecrypt decrypts input byte array using string password specified into a new (decrypted) byte array

   • pb.PBSignRequest signs an http request using a string password; adds 2 additional headers to the request

   • pb.PBVerifyRequest verifies previously signed http request using a string password

3. Paddings

   • pad.PKCS7Pad adds PKCS #7 padding to an input byte array, returning new (padded) byte array

   • pad.PKCS7Unpad removes PKCS #7 padding from an input byte array, returning new (striped) byte array;
     checks if padding is correct

   • pad.X923Pad adds ANSI X.923 padding to an input byte array, returning new (padded) byte array

   • pad.X923Unad removes ANSI X.923 padding from an input byte array, returning new (striped) byte array;
     checks if padding is correct

4. Random

   • rnd.RandomBytes generates a random byte array of the specified length

   • IV synonim for RandomBytes, used to generate random IV

   • Salt synonim for RandomBytes, used to generate random Salt

5. Asymetric Cryptography

   • asym.GenerateKeyPair generates private/public key pair, result is returned as two strings

   • asym.Sign signes a byte array (usually hash) using private key specified

   • asym.Verify verifies a byte array signature using public key specified
