Explicit parameter naming is optional on mandatory parameters, so both forms are “correct,” the question is which do you like better? Like vcsjones said, Resharper is just giving you some refactoring options to suit your preferences.
There is no such function built into SQLite3. But you could define a user function e.g. with sqlite3_create_function if you’re using the C interface, and implement SHA-1 with that. (But if you’re having a programmable interface perhaps you could just SHA-1 the password outside of the SQL engine.) You could also try to find / … Read more
LTV (Long Term Validation) and PDF signatures The term LTV-enabled 4 Profile for PAdES-LTV 4.1 Overview Validation of an electronic signature requires data to validate the signature such as CA certificates, Certificate Revocation List (CRLs) or Certificate status information (OCSP) commonly provided by an online service (referred to in the present document as validation data). … Read more
This answer reflects the comments from Luke Park, bartonjs, Timo, aand Maarten Bodewes above. One option is to use the Bouncycastle C# library, which has its own self-contained implementation of AES as well as the GCM mode. Look at the source code for the classes GCMBlockCipher, AesEngine, and AEADParameters. Another option is to use P/Invoke … Read more
The counter must return the same on decryption as it did on encryption, as you intuit, so, one (NOT SECURE AT ALL) way to do it is: >>> secret = os.urandom(16) >>> crypto = AES.new(os.urandom(32), AES.MODE_CTR, counter=lambda: secret) >>> encrypted = crypto.encrypt(“aaaaaaaaaaaaaaaa”) >>> print crypto.decrypt(encrypted) aaaaaaaaaaaaaaaa CTR is a block cipher, so the “16-at-a-time” constraint … Read more
KJKHyperion said in his answer: I discovered the “magic” sequence of calls to import a RSA public key in PEM format. Here you go: decode the key into a binary blob with CryptStringToBinary; pass CRYPT_STRING_BASE64HEADER in dwFlags decode the binary key blob into a CERT_PUBLIC_KEY_INFO with CryptDecodeObjectEx; pass X509_ASN_ENCODING in dwCertEncodingType and X509_PUBLIC_KEY_INFO in lpszStructType … Read more
If you target iOS 13.0+ or macOS 10.15+, use Apple’s CryptoKit import CryptoKit let secretString = “my-secret” let key = SymmetricKey(data: Data(secretString.utf8)) let string = “An apple a day keeps anyone away, if you throw it hard enough” let signature = HMAC<SHA256>.authenticationCode(for: Data(string.utf8), using: key) print(Data(signature).map { String(format: “%02hhx”, $0) }.joined()) // 1c161b971ab68e7acdb0b45cca7ae92d574613b77fca4bc7d5c4effab89dab67
I am afraid it is not possible to detect if the card containing specific X509Certificate2 object is present in the reader by using standard .NET APIs. The best thing (very hackish) I could come up with is this: public static X509Certificate2 GetDefaultCertificateStoredOnTheCard() { // Acquire public key stored in the default container of the currently … Read more

Your .key and .crt files may be in PEM format. To check this open them with a text editor and check whether the content looks like ——BEGIN CERTIFICATE—— (or “begin RSA private key”…). This is generally the default format used by OpenSSL, unless you’ve explicitly specified DER. It’s probably not required (see below), but if … Read more
