signature

问题 I'm trying to write a request for API coinbase.com, but I can not correctly generate a signature. I've been trying to find my mistake for 2 days, but I can not. I analyzed the code for other languages on the page: https://developers.coinbase.com/docs/wallet/api-key-autumnicathion but I do not see any differences in implementation. Help me please. <?php $g_coinbase_key = 'KcxisxqmWRVgtwsj'; $g_coinbase_secret = 'isOLGBLaEkCy3ROQMvmjonGmXK0KRmUS'; $time = time(); $method = "GET"; $path = '/v2

问题 I'm creating some email signatures for my company and I've come across a little problem. I've got it working with Outlook fine (when I send to a user with Outlook the signature looks perfect), however when they reply the signature text is turned into a .png file, while the background image is shown still. I'm not sure why Outlook is turning it into a .png? Has anyone experienced this ? IMAGES. This is how the signature should look, and does look in Outlook & Mac mail. This is what happens

问题 This question already has answers here : Supplied key param cannot be coerced into a private key with Google APIs (2 answers) Closed 4 years ago . I have this error with this file: <?php // $data and $signature are assumed to contain the data and the signature $signature = null; $toSign = "C:/Users/User/Desktop/xampp/htdocs/docum.docx"; $fp = fopen("key.pem", "r"); $priv_key = fread($fp, 8192); fclose($fp); $pkeyid = openssl_get_privatekey($priv_key); openssl_sign($toSign, $signature, $pkeyid

问题 I need help with jSignature. I am able to create an image and then write that image back into the page. What I can't get working (and the reason I was exploring this plugin in the first place) is the exporting of the image out of the page. I want to take the image data and send it out in an email so that the image shows up in the body of the email. If have tried a lot of approaches and nothing has worked. Currently my js looks like this: var $sigDiv = $("#signature").jSignature(); $('<input

问题 There are several questions on Stack Overflow about a method signature in C#. Almost all solutions say that a return value and access level are not parts of a method signature. But I found on MSDN completely opposite information. Methods are declared in a class or struct by specifying the access level such as public or private, optional modifiers such as abstract or sealed, the return value, the name of the method, and any method parameters. These parts together are the signature of the

问题 I am accessing a third party web service using JAX-WS generated client (Java) code. A call to a service that initiates a client session returns a Token in the response which, a.o., contains a Signature. The Token is required in subsequent calls to other services for authentication purposes. I learned from using SoapUI that the WS/Endpoint requires the Token to be used as-is... meaning everything works fine when I literally copy the Token (which is one big line) from the initial response to

问题 I have to sign a BlackBerry application so that I can load it onto the device, but the system that the signature keys I got from RIM are installed on got formatted. Now I am trying to install the signature keys on another system, but the server prompts me for this: "Unable to register client '2909103544' because there are no more registration attempts. If you have already registered with this server, then you must contact RIM to register additional user." Can we install these keys on only one

问题 I've two pdf documents certified (signed and validated with the same mechanism based on Itext 7 ) and when i use adobe reader DC to check their validity, only one has the green mark. the good one: https://1drv.ms/b/s!AkF6t4TavwMvgxWaidlUqvPvHH1r the bad one: https://1drv.ms/b/s!AkF6t4TavwMvgxQCMdGY61S1EvUh Regards David L 回答1: This is not an Adobe bug, it's a feature. (And an iText bug) When Adobe performs the cryptographic validation, it will also perform additional checks to see if a

问题 I want to do multiple signatures in a pdf document with iText7 , but the problem is when I have once sign , it works . If I sign twice , the first signature is invalid . It looks like this : unsigned PDF signed PDF and here is my code: @Test public void testMutiSign() { iTextSignerUtil1.SignMultPDF(getBytes(unsignedPath), destPath1); iTextSignerUtil2.SignMultPDF(getBytes(destPath1), destPath2); } IExternalSignatureContainer externalP7DetachSignatureContainer = new IExternalSignatureContainer(

问题 I'm trying to create a certificate (A) which is signed for other certificate (B) stored in a p12 keystore. This stored certificate (B) was added to the trusted certificate store of my local machine. Certificate A is used to sign a pdf document using bouncy castle 1.52 library, but the digital signature that I obtain in the signed document is invalid. I'm going to explain the steps done just if somebody can help me. First, I create a CSR from the p12 keystore(B): private static
