pki/aesgcm

Import path: github.com/InsideGallery/core/pki/aesgcm

aesgcm is the preferred AES-GCM import path. It re-exports the legacy pki/aes implementation with names that avoid a local collision with Go's standard crypto/aes package.

Main API

• Cipher is an alias for the legacy AES-GCM cipher type.
• New(size) creates a cipher with a random key.
• KeySize16, KeySize24, and KeySize32 are supported key sizes in bytes.
• ErrInvalidKeySize reports unsupported key sizes.
• Cipher.Encrypt, Cipher.Decrypt, Cipher.Kind, Cipher.ToBinary, and Cipher.FromBinary are inherited from pki/aes.

Usage

package example

import "github.com/InsideGallery/core/pki/aesgcm"

func roundTrip(plaintext []byte) ([]byte, error) {
	cipher, err := aesgcm.New(aesgcm.KeySize32)
	if err != nil {
		return nil, err
	}

	ciphertext, err := cipher.Encrypt(plaintext)
	if err != nil {
		return nil, err
	}

	return cipher.Decrypt(ciphertext)
}

Security and Compatibility Notes

Encryption uses AES-GCM with a random nonce, prefixes that nonce to the ciphertext, and hex-encodes the combined bytes. The implementation does not use additional authenticated data. github.com/InsideGallery/core/pki/aes remains available for existing consumers, but new code should import this package.
