I need a clear, step-by-step walkthrough that shows how the number 862882046310981 is transformed into the encrypted string 5a4ece668b2e02449a1a576120271ad8. • I already have the encryption algorithm in hand and will share it as soon as we start. • I’m not certain whether the method is symmetric or asymmetric, so please confirm that as part of your analysis. • I also have extra background on how the data was generated and will provide those details privately. Deliverables I expect: 1. A concise technical explanation of each stage in the encryption process. 2. Working code (Python preferred, but any clear language is fine) that reproduces the encrypted output from the plain number. 3. Brief notes on key properties of the algorithm—e.g., key length, mo...

I need a C# solution to apply RSA SHA1 digital signatures on an XML document with over 50 nodes. Each node should be signed individually, without URI references, and must be verifiable using C#. Requirements: - Use of 2048-bit RSA key PKCS#1 - Individual signatures for each XML node named <signedData> - No URI references for signatures - ds: NameSpace for Signature and child nodes of Signature, i.e <ds:Signature> - Enveloped method to include the Signature and Digest within the same Node, this should be appended as Child Node in <signedData> - = ; - = ; - XmlDsigC14NWithCommentsTransform env = new XmlDsigC14NWithCommentsTransform(); - XmlDsigEnvelopedSignatureTransform env = new XmlDsigEnvelopedSignatureTransform(); - Verification Module in C# included in the same sol...
