However, unlike RFC 's formulation, this package's private key representation includes a public key suffix to make multiple signing operations with the same key more efficient. Beginning with Go 1. This package only acts as a compatibility wrapper. Reader will be used. Sign signs the message with privateKey and returns a signature. It export folder and subfolder list to excel 2010 panic if len privateKey is not PrivateKeySize.

Verify reports whether sig is a valid signature of message by publicKey. It will panic if len publicKey is not PublicKeySize. NewKeyFromSeed calculates a private key from a seed. It will panic if len seed is not SeedSize. This function is provided for interoperability with RFC RFC 's private keys correspond to seeds in this package.

This is intended to be called from the init function in packages that implement hash functions. Decrypter is an interface for an opaque private key that can be used for asymmetric decryption operations.

An example would be an RSA key kept in a hardware module. New returns a new hash. Hash calculating the given hash function. New panics if the hash function is not linked into the binary. Size returns the length, in bytes, of a digest resulting from the given hash function.

Returns nil on success, or an error on failure. Cost returns the hashing cost used to create the given hashed password. When, in the future, the hashing cost of a password system needs to be increased in order to adjust for greater computational power, this function allows one to establish which passwords need to be updated. GenerateFromPassword returns the bcrypt hash of the password at the given cost. If the cost given is less than MinCost, the cost will be set to DefaultCost, instead.

Use CompareHashAndPassword, as defined in this package, to compare the returned hashed password with its cleartext version. The error returned from CompareHashAndPassword when a hash was created with a bcrypt algorithm newer than this implementation.

So, in this article I will explain the Golang crypto module with examples, and some use cases. I simple terms, cryptography is a digital technology that secures your data, like passwords, credit card number or anything which you want to secure.

It fulfills following four goals. Data integrity. The four points are linked to Wikipedia pages. To go in details, you can refer same, I will explain them in very short definitions. Non-repudiationis the party which is sending the data cannot deny, that they have not sent it. Cryptography algorithms are algorithms which are needed when we do crypt operations, like encryption, decryption, sign and verify. In layman terms, we are locking our data. So, for locking our data we need a key and to unlock it we need the key.

So all the cryptography is based on key. This was a small description of crypto, now in next parts. I will do a client server example for both.

Golang has a package, Golang Crypto. Which fulfills almost all the application crypto needs.
