Client-side encryption
open-in-new
<h2 id="details">Details</h2> <p>Client-side encryption seeks to eliminate the potential for data to be viewed by service providers (or third parties that compel service providers to deliver access to data), client-side encryption ensures that data and files that are stored in the cloud can only be viewed on the client-side of the exchange. This prevents data loss and the unauthorized disclosure of private or personal files, providing increased peace of mind for its users.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> </p><p>Current recommendations by industry professionals as well as academic scholars offer great vocal support for developers to include client-side encryption to protect the confidentiality and integrity of information. <a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a><a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> <a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> </p> <h3>Examples of services that use client-side encryption by default</h3> <ul><li><a href="/facts/Tresorit/yWEPvpJq">Tresorit</a><a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a></li> <li><a href="/facts/Mega_(service)/61VP5u2j">MEGA</a><a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a></li> <li><a href="/facts/Cryptee/G7RwMocm">Cryptee</a><a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a></li> <li><a href="/facts/Cryptomator/h3VvC4Cu">Cryptomator</a><a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a></li></ul> <h3>Examples of services that optionally support client-side encryption</h3> <ul><li><a href="/facts/ICloud/AUcIyg4L">Apple iCloud</a> offers optional client-side encryption when "Advanced Data Protection for iCloud" is enabled.<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a><a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a></li> <li><a href="/facts/Google_Drive/mgEjwvIs">Google Drive</a>,<a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a> <a href="/facts/Google_Docs/y2RYkhAQ">Google Docs</a>,<a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a> <a href="/facts/Google_Meet/qr6T0jWx">Google Meet</a>,<a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a> <a href="/facts/Google_Calendar/tgbSTAux">Google Calendar</a>,<a class="footnote-ref" id="fnref:17" href="#fn:17"><sup>17</sup></a> and <a href="/facts/Gmail/GXU2IQH4">Gmail</a><a class="footnote-ref" id="fnref:18" href="#fn:18"><sup>18</sup></a> — However, as of Jul 2024, optional client-side encryption features are only available to paid users.<a class="footnote-ref" id="fnref:19" href="#fn:19"><sup>19</sup></a></li></ul> <h3>Examples of services that do not support client-side encryption</h3> <ul><li><a href="/facts/Dropbox_(service)/1WHn5C7p">Dropbox</a><a class="footnote-ref" id="fnref:20" href="#fn:20"><sup>20</sup></a></li></ul> <h3>Examples of client-side encrypted services that no longer exist</h3> <ul><li><a href="/facts/SpiderOak/EhtC8nXs">SpiderOak Backup</a><a class="footnote-ref" id="fnref:21" href="#fn:21"><sup>21</sup></a></li></ul> <h2 id="see-also">See also</h2> <ul><li><a href="/facts/End-to-end_encryption/e1MwRzEU">End-to-end encryption</a> – the encryption of data between two different clients that are communicating with each other</li> <li><a href="/facts/Homomorphic_encryption/pbfGnqBn">Homomorphic encryption</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Tunio Gaffer (2015).
