Crypt2.SetEncodedKey – Help! I Passed a non-Hex String but Told Chilkat it was Hex
You made a mistake and set an AES encryption key in the wrong way like this: Chilkat.Crypt2 crypt = new Chilkat.Crypt2(); crypt.KeyLength = 256; crypt.CryptAlgorithm = “aes”; // This is the error. We passed base64 (or anything that is NOT a hexidecimal string) // And then asked Chilkat to decode it as hex. crypt.SetEncodedKey(“rZFNAfY7CirLtWxKiRU187k9mqcGCBZnV4QrmBvsboE”,”hex”); And […]

Be Careful when Using non-us-ascii String Literals in Source Code
When using non-US-ASCII literal strings (e.g., accented characters like “é”, “ü”, or symbols from other scripts like “你好”) in source code, it’s crucial to handle them carefully due to potential issues with encoding, interpretation, and compatibility. Here’s an explanation of key considerations: 1. Source Code File Encoding Encoding Matters: The source code file must be […]
FTP Rename Remote File – What Happens if the Target Remote File Already Exists?
The behavior of the FTP “RNTO” command when the target file already exists depends on the FTP server implementation and configuration. The File Transfer Protocol (FTP) itself, as defined in RFC 959, does not explicitly specify what should happen in this case, leaving it up to the server’s discretion. Typical Behaviors for “RNTO” When the […]
How ASN.1 Encodes Lengths
In ASN.1 (Abstract Syntax Notation One), lengths are encoded as part of the TLV (Type-Length-Value) structure, where each element consists of: Type: Identifies the data type of the element. Length: Specifies the number of bytes that make up the element’s content. Value: Contains the actual data or content. The Length field in ASN.1 encoding is […]
What is a .p7m or .p7s File?
“.p7m” and “.p7s” files are both related to PKCS #7 (Public Key Cryptography Standards #7) and are used for secure email and digital signatures. These files encapsulate data with cryptographic signatures and certificates to verify the identity of the sender and/or the integrity of the message. 1. “.p7m” File (Signed and Encrypted Content) Description: A […]
OCSP Nonce Lengths
In the OCSP (Online Certificate Status Protocol), the nonce is an optional field used to prevent replay attacks by ensuring that the OCSP response corresponds to the specific OCSP request. The nonce is a randomly generated value included in the OCSP request and echoed back in the response by the OCSP server. Nonce Length in […]
