Decoding incorrect(?) ASN.1 OID in an X.509 certificate
I'm writing a small utility to manually decode and extract an RSA public key from an X.509 certificate. It seems to have worked fine so far, but recently failed for a test certificate. Here's why: While decoding the ASN.1 OID, I'm expecting '2a 86 48 86 f7 0d 01 01 01', which decodes to 1.2.840.113549.1.1.1 (rsaEncryption). The certific...
How I can encrypt a string in c #?

Signing a string with RSA private key on .NET?
byte[] plaintext = System.Text.Encoding.UTF8.GetBytes("AAAAAAAAAAAAA"); TextReader trCer = new StreamReader(@"AA.key"); //key in PEM format PemReader rdCer = new PemReader(trCer); AsymmetricCipherKeyPair o = rdCer.ReadObject() as AsymmetricCipherKeyPair; ISigner sig = SignerUtilities.GetSigner("MD5WithRSAEncryption"); sig.Init(true,...
Write x509 certificate into PEM formatted string in java?
Is there some high level way to write an X509Certificate into a PEM formatted string? Currently I'm doing x509cert.encode() to write it into a DER formatted string, then base 64 encoding it and appending the header and footer to create a PEM string, but it seems bad. Especially since I have to throw in line breaks too. ...
