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

rsaoaep is the preferred RSA-OAEP import path. It re-exports the legacy pki/rsa implementation with names that avoid a local collision with Go's standard crypto/rsa package.

Main API

• Cipher is an alias for the legacy RSA-OAEP cipher type.
• New(bits) generates a new RSA private key and matching public key.
• FromPrivateKey(data) restores a cipher from PKCS#1 private-key PEM data.
• DefaultKeyBits is the default key size, currently 4096 bits.
• PrivateKeyPEMBlockType is the PEM block type used by ToBinary.
• ErrFailedToParsePEMBlock reports data that is not a private-key PEM block.
• Cipher.Encrypt, Cipher.Decrypt, Cipher.Kind, Cipher.ToBinary, and Cipher.FromBinary are inherited from pki/rsa.

Usage

package example

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

func restoreAndDecrypt(privateKeyPEM, ciphertext []byte) ([]byte, error) {
	cipher, err := rsaoaep.FromPrivateKey(privateKeyPEM)
	if err != nil {
		return nil, err
	}

	return cipher.Decrypt(ciphertext)
}

Security and Compatibility Notes

Encryption uses RSA-OAEP with SHA-256 and a nil label. RSA-OAEP is suited to short payloads such as wrapped keys. github.com/InsideGallery/core/pki/rsa remains available for existing consumers, but new code should import this package.
