function wc_InitSha512

int wc_InitSha512(
    wc_Sha512 * 
)

This function initializes SHA512. This is automatically called by wc_Sha512Hash.

Parameters:

• sha512 pointer to the sha512 structure to use for encryption

See:

• wc_Sha512Hash
• wc_Sha512Update
• wc_Sha512Final

Return: 0 Returned upon successfully initializing

Example

Sha512 sha512[1];
if ((ret = wc_InitSha512(sha512)) != 0) {
   WOLFSSL_MSG("wc_InitSha512 failed");
}
else {
   wc_Sha512Update(sha512, data, len);
   wc_Sha512Final(sha512, hash);
}

function wc_Sha512Update

int wc_Sha512Update(
    wc_Sha512 * sha,
    const byte * data,
    word32 len
)

Can be called to continually hash the provided byte array of length len.

Parameters:

• sha512 pointer to the sha512 structure to use for encryption
• data the data to be hashed
• len length of data to be hashed

See:

• wc_Sha512Hash
• wc_Sha512Final
• wc_InitSha512

Return: 0 Returned upon successfully adding the data to the digest.

Example

Sha512 sha512[1];
byte data[] = { Data to be hashed };
word32 len = sizeof(data);

if ((ret = wc_InitSha512(sha512)) != 0) {
   WOLFSSL_MSG("wc_InitSha512 failed");
}
else {
   wc_Sha512Update(sha512, data, len);
   wc_Sha512Final(sha512, hash);
}

function wc_Sha512Final

int wc_Sha512Final(
    wc_Sha512 * sha512,
    byte * hash
)

Finalizes hashing of data. Result is placed into hash.

Parameters:

• sha512 pointer to the sha512 structure to use for encryption
• hash Byte array to hold hash value.

See:

• wc_Sha512Hash
• wc_Sha512Final
• wc_InitSha512

Return: 0 Returned upon successfully finalizing the hash.

Example

Sha512 sha512[1];
byte data[] = { Data to be hashed };
word32 len = sizeof(data);

if ((ret = wc_InitSha512(sha512)) != 0) {
    WOLFSSL_MSG("wc_InitSha512 failed");
}
else {
   wc_Sha512Update(sha512, data, len);

Example

Sha384 sha384[1];
if ((ret = wc_InitSha384(sha384)) != 0) {
   WOLFSSL_MSG("wc_InitSha384 failed");
}
else {
   wc_Sha384Update(sha384, data, len);
   wc_Sha384Final(sha384, hash);
}

function wc_Sha384Update

int wc_Sha384Update(
    wc_Sha384 * sha,
