For an application I want to write, the webservice gives me this public key, with which I have to encrypt the password for signing in. But I don't know what kind of encryption this might be. Is this recognisable? Is it possible to tell what this is or do I have to find it out my own by sniffing into the JavaScript (of the web GUI) which handles this key?
Here it is:
-----BEGIN PUBLIC KEY----- MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDN+SsAsYvIstaZ\/SYUNv7wvr+a Ajkc28XxuKWpCbqFQS+EWeYpbuBB88iJU98yFjsFMh5BLbXhEX+2JmrC0DWd6o3r 1ILhNL27KmXo6Dh+2y0b9l3YXtmwiA1ThZEQun4Z1rUBPMF43DF805keLIsASFpj nzc6zWw+jYCX7PTasQIDAQAB -----END PUBLIC KEY-----
The fact that there is PUBLIC KEY, indicates this is asymmetric encryption. But there are lots of it. Here is a list, taken from Wikipedia of asymmetric encryption methods:
Benaloh · Blum–Goldwasser · Cayley–Purser · CEILIDH · Cramer–Shoup · Damgård–Jurik · DH · DSA · EPOC · ECDH · ECDSA · EKE · ElGamal (encryption · signature scheme) · GMR · Goldwasser–Micali · HFE · IES · Lamport · McEliece · Merkle–Hellman · MQV · Naccache–Stern · NTRUEncrypt · NTRUSign · Paillier · Rabin · RSA · Okamoto–Uchiyama · Schnorr · Schmidt–Samoa · SPEKE · SRP · STS · Three-pass protocol · XTR
RSA is the only one I know by it's name. Is that the most common one?
Thanks you very much for the help.
It's a 1024-bit RSA public key in PEM format with one character mangled in the first line:
