Struct Md 

pub struct Md(/* private fields */);

A message digest algorithm.

Implementations

impl Md

pub fn from_nid(type_: Nid) -> Option<&'static MdRef>

Returns the Md corresponding to an Nid.

This corresponds to EVP_get_digestbynid.

pub fn fetch( ctx: Option<&LibCtxRef>, algorithm: &str, properties: Option<&str>, ) -> Result<Self, ErrorStack>

Fetches an Md object corresponding to the specified algorithm name and properties.

Requires OpenSSL 3.0.0 or newer.

This corresponds to EVP_MD_fetch.

pub fn null() -> &'static MdRef

pub fn md5() -> &'static MdRef

pub fn sha1() -> &'static MdRef

pub fn sha224() -> &'static MdRef

pub fn sha256() -> &'static MdRef

pub fn sha384() -> &'static MdRef

pub fn sha512() -> &'static MdRef

pub fn sha3_224() -> &'static MdRef

pub fn sha3_256() -> &'static MdRef

pub fn sha3_384() -> &'static MdRef

pub fn sha3_512() -> &'static MdRef

pub fn shake128() -> &'static MdRef

pub fn shake256() -> &'static MdRef

pub fn ripemd160() -> &'static MdRef

pub fn sm3() -> &'static MdRef

Methods from Deref<Target = MdRef>

pub fn block_size(&self) -> usize

Returns the block size of the digest in bytes.

This corresponds to EVP_MD_block_size.

pub fn size(&self) -> usize

Returns the size of the digest in bytes.

This corresponds to EVP_MD_size.

pub fn type_(&self) -> Nid

Returns the Nid of the digest.

This corresponds to EVP_MD_type.

Trait Implementations

impl Deref for Md

type Target = MdRef

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for Md

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl Drop for Md

fn drop(&mut self)

Executes the destructor for this type.

impl ForeignType for Md

type CType = EVP_MD

The raw C type.

type Ref = MdRef

The type representing a reference to this type.

unsafe fn from_ptr(ptr: *mut Self::CType) -> Self

Constructs an instance of this type from its raw type.

fn as_ptr(&self) -> *mut Self::CType

Returns a raw pointer to the wrapped value.

impl Send for Md

impl Sync for Md

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
