(Go) RSA Decrypt using PEMThis example demonstrates decryping RSA encrypted data that is base64 encoded. It uses a private key loaded from a PEM file.
// This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. rsa := chilkat.NewRsa() key := chilkat.NewPrivateKey() // Load an RSA private key from an unencrypted PEM file: // (To load from an encrypted PEM file, call LoadEncryptedPemFile instead.) success := key.LoadPemFile("qa_data/rsa/decryptTest/priv.pem") if success != true { fmt.Println(key.LastErrorText()) rsa.DisposeRsa() key.DisposePrivateKey() return } // Make the key available to the RSA object success = rsa.ImportPrivateKeyObj(key) if success != true { fmt.Println(rsa.LastErrorText()) rsa.DisposeRsa() key.DisposePrivateKey() return } encryptedStr := "pP9XFJEsGgxPNHEgNiLB5H5ksCOXDk/G49BPTog1jKLAhYofV4UTH5k2TOYiqRnDnKs8+8uPoN/IxdiGXvuYG8HRzN0HtkhoZO/AxeyaB9S7eddCUlT0Pl2PEB2yQ9HG5rM7jqYOD6MAM4cuX7hqT8fa8tbzJzmBwdfFDBz94bwQjULHiO+gklIBC4vhkXT4yjuvEjxTAKU6tJeZYkBooJNdS/vE5RZRpuF6bGZU41Qc17qFR+iReBq+9f8IMmw8WR8fMbOCaygOfFS1nw7JVsIMGsAIXS8rUaJ/2DfGPfQx5HCiVtTOreGYRUI3esAQjnvUCnavZyQgs53nl7e2aA==" rsa.SetEncodingMode("base64") usePrivateKey := true decryptedStr := rsa.DecryptStringENC(encryptedStr,usePrivateKey) fmt.Println("Decrypted:") fmt.Println(*decryptedStr) rsa.DisposeRsa() key.DisposePrivateKey() |
