<h3>How to sign and verify a text message (simple usage)</h3>
|
||
|
|
<ol>
|
||
|
|
<li>Modify the text message 'aaa' to anything you want.</li>
|
||
|
|
<li>Choose hash algorithm for signing 'SHA1' or 'SHA256'.</li>
|
||
|
|
<li>Push 'Sign to this message' button in the left.</li>
|
||
|
|
<li>Push 'Copy' button in the middle to copy the message to be signed and the generated signature value to verification form in the right.</li>
|
||
|
|
<li>Push 'Verify this message' in the right.</li>
|
||
|
|
<li>Then you can see signature verification result in the top of right.</li>
|
||
|
|
</ol>
|
||
|
|
<h3>Note for signing in the left form.</h3>
|
||
|
|
See below when you want to specify message and private key to be signed.
|
||
|
|
<ul>
|
||
|
|
<li>In the 'PEM RSA Private Key' text area, you can specify
|
||
|
|
signer's private key. The format of the key should be
|
||
|
|
PKCS#1 PEM text formatted and unencrypted RSA private key.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<h3>Note for signature verification in the right form.</h3>
|
||
|
|
See below when you want to specify message,
|
||
|
|
signature value and public key certificate to be verified.
|
||
|
|
<ul>
|
||
|
|
<li>In the 'Verifying Signature' field, you can specify
|
||
|
|
any signature value to be verified.
|
||
|
|
Signature value should be hexa decimal encoded 'RSASSA-PKCS1-v1_5' signature.
|
||
|
|
Currently this supports 'SHA1withRSA' and 'SHA256withRSA' signature algorihtm.
|
||
|
|
RSA key length have been tested from 512bit to 2048bit for this program.
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
In the "Signer's Public Key Certificate" field,
|
||
|
|
you can specify signer's public key certificate to be verified.
|
||
|
|
The value should be PEM encoded X.509 certificate with RSA public key.
|
||
|
|
X.509v1 and X.509v3 is available however X.509v2 is not supported now.
|
||
|
|
