PaddingScheme

No padding. Useful when the block size is 8 bits for block cipher streaming operations. (Because a byte is the most primitive block size, there is nothing to pad).

Padding scheme as defined in the W3C's &quot;XML Encryption Syntax and Processing&quot; document, <a href="http://www.w3.org/TR/xmlenc-core/#sec-Alg-Block">Section 5.2 - Block Encryption Algorithms</a>.

Optimal Asymmetric Encryption Padding defined in RSA's <a href="http://en.wikipedia.org/wiki/PKCS1">PKSC#1 standard</a> (aka <a href="http://tools.ietf.org/html/rfc3447">RFC 3447</a>). <p/> <b>NOTE:</b> using this padding requires initializing {@link javax.crypto.Cipher Cipher} instances with a {@link javax.crypto.spec.OAEPParameterSpec OAEPParameterSpec} object which provides the 1) message digest and 2) mask generation function to use for the scheme. <h3>Convenient Alternatives</h3> While using this scheme enables you full customization of the message digest + mask generation function combination, it does require the extra burden of providing your own {@code OAEPParameterSpec} object. This is often unnecessary, because most combinations are fairly standard. These common combinations are pre-defined in this enum in the {@code OAEP}* variants. <p/> If you find that these common combinations still do not meet your needs, then you will need to specify your own message digest and mask generation function, either as an {@code OAEPParameterSpec} object during Cipher initialization or, maybe more easily, in the scheme name directly. If you want to use scheme name approach, the name format is specified in the <a href="http://java.sun.com/javase/6/docs/technotes/guides/security/StandardNames.html">Standard Names</a> document in the <code>Cipher Algorithm Padding</code> section.

Optimal Asymmetric Encryption Padding with {@code MD5} message digest and {@code MGF1} mask generation function. <p/> This is a convenient pre-defined OAEP padding scheme that embeds the message digest and mask generation function. When using this padding scheme, there is no need to init the {@code Cipher} instance with an {@link javax.crypto.spec.OAEPParameterSpec OAEPParameterSpec} object, as it is already 'built in' to the scheme name (unlike the {@link #OAEP OAEP} scheme, which requires a bit more work).

Optimal Asymmetric Encryption Padding with {@code SHA-1} message digest and {@code MGF1} mask generation function. <p/> This is a convenient pre-defined OAEP padding scheme that embeds the message digest and mask generation function. When using this padding scheme, there is no need to init the {@code Cipher} instance with an {@link javax.crypto.spec.OAEPParameterSpec OAEPParameterSpec} object, as it is already 'built in' to the scheme name (unlike the {@link #OAEP OAEP} scheme, which requires a bit more work).

Optimal Asymmetric Encryption Padding with {@code SHA-256} message digest and {@code MGF1} mask generation function. <p/> This is a convenient pre-defined OAEP padding scheme that embeds the message digest and mask generation function. When using this padding scheme, there is no need to init the {@code Cipher} instance with an {@link javax.crypto.spec.OAEPParameterSpec OAEPParameterSpec} object, as it is already 'built in' to the scheme name (unlike the {@link #OAEP OAEP} scheme, which requires a bit more work).

Optimal Asymmetric Encryption Padding with {@code SHA-384} message digest and {@code MGF1} mask generation function. <p/> This is a convenient pre-defined OAEP padding scheme that embeds the message digest and mask generation function. When using this padding scheme, there is no need to init the {@code Cipher} instance with an {@link javax.crypto.spec.OAEPParameterSpec OAEPParameterSpec} object, as it is already 'built in' to the scheme name (unlike the {@link #OAEP OAEP} scheme, which requires a bit more work).

Optimal Asymmetric Encryption Padding with {@code SHA-512} message digest and {@code MGF1} mask generation function. <p/> This is a convenient pre-defined OAEP padding scheme that embeds the message digest and mask generation function. When using this padding scheme, there is no need to init the {@code Cipher} instance with an {@link javax.crypto.spec.OAEPParameterSpec OAEPParameterSpec} object, as it is already 'built in' to the scheme name (unlike the {@link #OAEP OAEP} scheme, which requires a bit more work).
