+&nbsp;&nbsp;&nbsp;&nbsp;&lt;pre&nbsp;wrap=&quot;&quot;&gt;Hi&nbsp;everyone,<br>
+<br>
+I&nbsp;am&nbsp;trying&nbsp;to&nbsp;implement&nbsp;a&nbsp;simple&nbsp;pub/private&nbsp;key&nbsp;scheme.&nbsp;Want&nbsp;to&nbsp;encrypt&nbsp;bunch&nbsp;of&nbsp;things&nbsp;and&nbsp;decrypt&nbsp;it&nbsp;using&nbsp;public<br>
+key&nbsp;(which&nbsp;will&nbsp;be&nbsp;distributed).<br>

+You&nbsp;seem&nbsp;to&nbsp;have&nbsp;some&nbsp;misconceptions&nbsp;about&nbsp;how&nbsp;public&nbsp;key&nbsp;cryptography&nbsp;works.<br>
+I&nbsp;suggest&nbsp;you&nbsp;(re-)read&nbsp;up&nbsp;on&nbsp;it.&nbsp;Wikipedia&nbsp;will&nbsp;probably&nbsp;cover&nbsp;the&nbsp;basics.<br>
+For&nbsp;starters,&nbsp;by&nbsp;definition&nbsp;you&nbsp;use&nbsp;the&nbsp;*public*&nbsp;key&nbsp;for&nbsp;encrypt&nbsp;and&nbsp;the&nbsp;privat&nbsp;one&nbsp;for&nbsp;decryption.<br>
+&nbsp;&nbsp;&lt;/pre&gt;<br>
+&lt;/blockquote&gt;<br>
+&lt;br&gt;<br>
+Indeed,&nbsp;Wikipedia&nbsp;has&nbsp;an&nbsp;article.&amp;nbsp;&nbsp;And&nbsp;in&nbsp;the&nbsp;first&nbsp;paragraph&nbsp;[1]&nbsp;they<br>
+describe&nbsp;one&nbsp;use&nbsp;case&nbsp;for&nbsp;encrypting&nbsp;by&nbsp;public&nbsp;key,&nbsp;and&nbsp;decrypting&nbsp;by<br>
+private&nbsp;key,&nbsp;and&nbsp;another&nbsp;use&nbsp;case&nbsp;for&nbsp;encrypting&nbsp;by&nbsp;private&nbsp;key,&nbsp;and<br>
+decrypting&nbsp;by&nbsp;public&nbsp;key.&amp;nbsp;&nbsp;It&nbsp;might&nbsp;be&nbsp;appropriate&nbsp;to&nbsp;figure&nbsp;out&nbsp;what<br>
+use&nbsp;case&nbsp;the&nbsp;OP&nbsp;has&nbsp;before&nbsp;declaring&nbsp;definitions&nbsp;for&nbsp;a&nbsp;particular&nbsp;use<br>
+case.&amp;nbsp;&nbsp;Now&nbsp;as&nbsp;far&nbsp;as&nbsp;what&nbsp;the&nbsp;APIs&nbsp;are&nbsp;called,&nbsp;that&nbsp;might&nbsp;be&nbsp;a<br>
+different&nbsp;story&nbsp;:)&lt;br&gt;<br>

+and&nbsp;receiver.&nbsp;The&nbsp;asymmetric&nbsp;key&nbsp;algorithms&nbsp;are&nbsp;used&nbsp;to&nbsp;create&nbsp;a<br>
+mathematically&nbsp;related&nbsp;key&nbsp;pair:&nbsp;a&nbsp;secret&nbsp;private&nbsp;key&nbsp;and&nbsp;a&nbsp;published<br>
