QUESTION
I am going to say in advance i don't know too much about cryptography (Basics only). I am trying to Implement a Credential OpenHome Service and I want to encrypt a password to send it to the device.
The device provides a function written in C that returns a public key String that looks like that:

On iOS if you want to encrypt/decrypt you need to use a key stored on the keychain. If, in my case, i have been given the public key i can import it and also I can do the same with the private key. Please see my HelperClass Here.
Then, and from only from iOS 10, you can call this 2 methods for encrypting and decrypting
QUESTION
I want to user SWCrypt for RSA encryption and decryption. i should send my public key base64 decoded to server. but when i try send generated public key base64 i can't get this error in server side:
...ANSWER
Answered 2017-Jul-04 at 10:07X509 is a standard for Public Key Infraestructure, not a encoding format. You can encode a X509 public key in PEM
(base64), DER
(binary) or XML
. Also the binary data of the public key can be represented in PCKS#1
or X509 SubjectPublicKeyInfo
.
In my knowledge PKCS#8 is a standard for private keys. See PKCS #8: Private-Key Information Syntax Standard. So I guess SWCrypt is really using X509 SubjectPublicKeyInfo
(Maybe i have not read some RFCs), which is what your server is waiting for.
