Synopsis
Official Name: MD5Final
Other Name: FinishMD5
BCALL Address: 8018
Finishes an MD5 hash by adding padding and length bits.
Inputs
- 8269: (8 bytes) Holds the length in bits of the data hashed so far.
- 8292: (16 bytes) Current MD5 hash
Outputs
- 8292: (16 bytes) Completed MD5 hash
Destroys
- 8259: (16 bytes) Alternate registers (roughly equivalent to the AA, BB, CC, and DD registers specified in the MD5 standard.)
- 83A5: (64 bytes) Buffer holding data to be hashed.
Comments
This B_CALL "completes" a hash started by MD5Init and MD5Update.
Example
B_CALL MD5Init ld bc,14 ld hl,String B_CALL MD5Update B_CALL MD5Final ; should give: f96b 697d7cb7938d525a2f31aaf161d0 String: .db "message digest"
