/**
 * @module CertificateCard
 * The CertificateCard component receives data and optionally receives a boolean declaring if that data is meant to be in PEM
 * Format. It renders using the <HDS::Card::Container>. To the left there is a certificate icon. In the center there is a label
 * which says which format (PEM or DER) the data is in. Below the label is the truncated data. To the right there is a copy
 * button to copy the data.
 *
 * @example
 * ```js
 *  <CertificateCard @data={{value}} @isPem={{true}} />
 * ```
 * @param {string} data - the data to be displayed in the component (usually in PEM or DER format)
 * @param {boolean} isPem - optional argument for if the data is required to be in PEM format (and should thus have the PEM Format label)
