API Reference

XSTATUS XMD5_Compute(uint8_t *pOutput, size_t nSize, const uint8_t *pInput, size_t nLength)

  • Arguments:
    • pOutput: destination digest buffer.
    • nSize: destination size, must be at least 16.
    • pInput: input bytes.
    • nLength: input length.
  • Does:
    • computes raw 16-byte MD5 digest.
  • Returns:
    • XSTDOK on success.
    • XSTDINV on invalid args such as zero length or too-small output.
    • XSTDERR on allocation/internal failure.

uint8_t *XMD5_Encrypt(const uint8_t *pInput, size_t nLength)

  • Arguments:
    • pInput: input bytes.
    • nLength: input length.
  • Does:
    • computes MD5 and returns raw digest bytes.
  • Returns:
    • allocated 16 + 1 buffer or NULL.

char *XMD5_Sum(const uint8_t *pInput, size_t nLength)

  • Arguments:
    • input bytes and length.
  • Does:
    • computes MD5 and renders lowercase 32-character hex.
  • Returns:
    • allocated string or NULL.
