A tame penalty denied Sadio Mane a hat-trick against Kenya but the Liverpool forward still managed to twice get on the scoresheet in a 3-0 win to ensure Senegal booked a place in the last 16 of the 2019 Africa Cup of Nations.
Mane, 27, stepped up to take a first-half penalty but his effort was easily gathered by Patrick Matasi low to his right.
Mane did make amends with two second-half strikes - the second from the penalty spot - after Ismaila Sarr put Senegal ahead on 63 minutes with Kenya finishing the match with 10 men following Philemon Otieno's sending off.
Joining them in the knockout round are Algeria with a perfect record thanks to an identical 3-0 win over Tanzania, who bowed out of their first Cup of Nations appearance in almost 40 years with three defeats.
Adam Ounas scored twice and Islam Slimani also netted in what was largely a second-string side for the North African side.
Senegal finished runners-up in the group with six points.
Algeria and Senegal join already-qualified hosts Egypt, surprise outfit Madagascar and Morocco as well as Uganda, Nigeria and Ivory Coast, runners-up from Groups A, B and D respectively.
Defending champions Cameroon and Mali play on Tuesday and will finish third at worst in their groups, which would see them both advance as two of the four best third-placed teams.
Guinea and the Democratic Republic of Congo have already taken two of the spots.
There was plenty of drama in the first half at Cairo's 30 June Stadium with Senegal claiming a penalty after Kenya captain Victor Wanyama appeared to handle following a corner but Egyptian referee Ghead Grisha was unmoved.
Shortly afterwards, Kenya's Musa Mohammed clumsily tripped Saliou Ciss in the area and this time there was no let-off as the official pointed to the spot.
However, Matasi dived to his right to save Champions League-winning forward Mane's spot kick.
Matasi repelled efforts from Henri Saivet and Sarr before the break but was at fault for Senegal's opener when he failed to intercept a cross allowing Sarr to poke home just past the hour mark.
A quick counter-attack on 71 minutes saw Mane released to drill the ball past Matasi. By now Kenya looked ragged and Otieno was shown a second yellow card when he tripped Sarr in desperation. Mane stepped up and made no mistake second time around.
Senegal manager Aliou Cisse had been reluctant to allow Mane to take the second penalty but said it was the correct decision.
"He was right, it's important that he takes that responsibility, and it's important that he gets that confidence," Cisse told reporters.
"We were not so far, but not so close. If you commit a mistake, you are punished immediately when you play Senegal," said Kenya manager Sebastien Migne.
